Titrant Definition Chemistry Glossary

In analytical chemistry, the titrant is a solution of known concentration that is added (titrated) to another solution to determine the concentration of a second chemical species. The titrant may also be called the titrator, the reagent, or the standard solution. In contrast, the analyte, or titrand, is the species of interest during a titration. When a known concentration and volume of titrant is reacted with the analyte, its possible to determine the analyte concentration. How It Works The mole ratio between the reactants and products in a chemical equation is the key to using titration to determine an unknown concentration of a solution. Typically, a flask or beaker containing a precisely known volume of analyte, together with an indicator, is placed under a calibrated burette or pipette. The burette or pipette contains the titrant, which is added dropwise until the indicator shows a color change, indicating the titration endpoint. Color change indicators are tricky, because the color may temporarily change before permanently changing. This introduces some degree of error into the calculation. When the endpoint is reached, the volume of reactant is determined using the equation: Ca CtVtM/Va Where Ca is the analyte concentration (usually given as molarity), Ct is titrant concentration (in the same units), Vt is the volume of titrant required to reach the endpoint (usually in liters), M is the mole ratio between the analyte and reactant from the balanced equation, and Va is the analyte volume (usually in liters).

Coca Cola Company Industry Responses †Myassignmenthelp.com

Question: Discuss about theCoca Cola Company Industry Responses. Answer: Introduction Organizations international operations are shaped by industry pressure for local responsiveness and industry pressure for global integration. Operating in foreign country necessities certain requirements and developments to ensure the business continues with it mission. Industry pressure for local responsiveness refers to local requirements from the society (consumers) and the government that shape companys products and operations in a country. Industry pressure for global integration is the pressure that the company faces in the global arena in order to maintain competitiveness.1 Coca Cola is a multinational Company that manufactures non-alcoholic drinks. The drinks are distributed throughout the world market by licensed bottling company. The company has changed its products and operations in the recent years as a responsive to industry pressure. The company coco cola drink is a leading brand in Australian market. This paper outlines how Coca Cola Company is responding to pressure from both local responsiveness and global integration. The paper will also use examples in the local market of how Coca Cola Company is responding and international responses in order to remain the market leader in the non alcoholic drinks in the world market Industry Pressure for Local Responsiveness Coca Cola Company manufactures drinks for human consumption. Human beings are dynamic and keep on evolving from time to time. When other factors change in the society, people change their behavior in consuming specific products. For instance, level of education and level of income change individuals existing lifestyles and consequently change their consumption habits . For survival and improvement purposes, Coca Cola Company have to respond accordingly to local consumers and the government to ensure that it operations and products are not coherent with the domestic market.2 The following are responses that the coca cola company is doing to manage industry pressure from local responsiveness; Product differentiations: Coca Cola has continually introduced differentiated coke products that are tailored for specific segments in the Australia market. It has introduced coke zero and coke diet and still maintained the classic coke drink. The coke zero is meant for the increasing health conscious individuals in the market who suffer obesity. Coke diet is for the market segments who want drinks that have specific diet requirement. 1 Peter G.P. Walters, Paul Whitla and Howard Davies, "Global Strategy In The International Advertising Industry" (2008) 17 International Business Review. 2 Peter J. Buckley, "Business History And International Business" (2009) 51 Business History. Product substitution: The Company has recently and increasingly produced new drinks to market. This has been as a result of industry pressure from the local consumers who need substitute drinks. The company recently introduced bottle water in Australian market to act as a substitute to it products. Increasing cost of recycling: The Company has been facing legal charges on issues of recycling where the local government require them to recycle it by products. The company has responded by increasing its investment in recycling project to ensure that it within the environmental requirements of the government. Industry Pressure for Global Integration Coca Cola Company operates on international standards and face competitions from several companies. The company has to respond accordingly to ensure that the industry pressure for global integration does not slow down or dismantle its objectives. Due to technological advancement the company has continuously changed to maintain competitiveness in the industry .4 .The following are the responses that the company has done to manage industrial pressure for global integration; Cost reduction: The Company has improved efficiency and effectiveness in production by adopting technology in the process to reduce cost of production. All companies in the industry are striving to produce at the least possible cost so that it can offer drinks to the global market at a competitive prices. Production in large scale: Coca cola has increased its production per time. This response is aimed at ensuring that the company benefit from economies of scale. This minimizes the cost that the company incurs in manufacturing, processing and transportation. Due to industry pressure to sell products at competitive prices, the company has to operate in large scale in order to be able to compete successfully. Healthy products: The global market is evolving to consume products that are healthy to their bodies. Consumers have been changing their lifestyle to be health conscious of the product they consume. This has resulted to companies in the food and drinks industries to change products. Coca cola Company has responded to producing products that are healthy to ensure that it survives in the market competitively in the 21st century. 3 3 Claude Cellich, "Dynamics Of Successful International Business Negotiations" (1994) 3 International Business Review. 4 Yadong Luo, Entry And Cooperative Strategies In International Business Expansion (Quorum, 1st ed, 1999). Conclusion From the discussion above, it can be summarized that international business cannot remain static to industry pressure and has to keep responding in order to survive. Therefore it important that an international business keeps trends in both the local market and global arena References Buckley, Peter J., "Business History And International Business" (2009) 51 Business History Cellich, Claude, "Dynamics Of Successful International Business Negotiations" (1994) 3 International Business Review Company, Our et al, Coca-Cola Journey Homepage (2016) The Coca-Cola Company https://www.coca-colacompany.com/ Eliasson, Gunnar, "Global Economic Intergration And Regional Attractors Of Competence" (2003) 10 Industry Innovation Luo, Yadong, Entry And Cooperative Strategies In International Business Expansion (Quorum, 1st ed, 1999) Walters, Peter G.P., Paul Whitla and Howard Davies, "Global Strategy In The International Advertising Industry" (2008) 17 International Business Review

Why Is There Gravity Essays - Physics, Theoretical Physics

Why Is There Gravity? When you pick up a stone and release it falls to the ground. This seemingly simple concept has been known throughout history as gravitation. Isaac Newton managed to explain gravity in terms of its effects, but few have come up with a working explanation for the driving force behind it. The mysterious nature of some of the more peculiar effects of gravity, as well as the simple ones, indicate that explaining why there is gravity will be a long, difficult, yet intriguing task. Ohanian (1976) writes that without other forces interfering, mass attracts mass. This is the fundamental concept behind gravitation. Newton explained it as "there is a power of gravity pertaining to all bodies, proportional to the several quantities of matter which they contain? The force of gravity towards the several equal parts of any body is inversely as the square of the distance of places from the particles." This description of gravity creates the simple mathematical explanation of gravity: that the force of attraction, F, equals G * ((m1 * m2) / r^2). This holds true for most gravitational interactions on earth, so any proper theory of gravity would have to include similar results for these interactions. Misner, Thorne, and Wheeler (1973) explain that there are, however, some more complex aspects of gravity that this law does not account for. One of these strange gravitational effects is observed in the "perihelion shift" movement of planets, the most dramatically affected of which is the planet Mercury. Feynman, Leighton, and Sands (1963) contest that another hole in Newton's predictions about gravitation is that repercussions of changes in gravitational state are felt instantaneously. In other words, gravitational effects travel faster than the speed of light, which is in direct contradiction with Albert Einstein's Special Theory of Relativity. This led Einstein to develop a more advanced theory of gravitation. This was known as the General Theory of Relativity and is the closest and only thing that mankind has as an answer to " Why is there gravity?" Einstein's General Theory of Relativity introduces the idea that space itself can be curved. Just as the ground on earth appears to be flat though it is actually curved, Einstein suggested that space may behave much in the same way. Misner et al. (1973) compared the curvature of space to an ant walking on the surface of an apple whose direction was perfectly toward the stem of the apple. The shortest possible path on the surface of the apple to the stem was a curved line. Thus Einstein has theorized that the shortest possible path in a gravitational field is actually a curve, which is contrary to traditional Euclidean geometry. The other basic concept of general relativity is that gravity is essentially indistinguishable from acceleration. A person standing inside of a stationary elevator on earth could drop a ball and it would fall, accelerating at approximately 9.8m/s^2. A person standing in an elevator free from gravitational fields, but accelerating upwardly at 9.8m/s^2 would exp erience the same effect. Einstein used this similarity between gravity and acceleration in the creation of the General Theory of Relativity. One of the most stunning things about Einstein's theories is that they were created with virtually no experimental verification. Only later, after his death, have we been able to prove various aspects of the General Theory of Relativity experimentally. In this sense, Einstein was well ahead of his time. One such prediction that was ahead of its time was that time moves slower in the presence of a gravitational field. In Einstein's day, they simply did not have the resources to test this experimentally. In more recent times, however, through the use of atomic clocks we have shown this to be true. It is certainly amazing to make predictions about something so abstract on a purely theoretical basis and then later have those predictions verified through experimentation. Unfortunately, Einstein's General Theory of Relativity is the only theory of gravity that has never failed experimentally. Other theories that work experimentally are essentially tweaked versions of the same ideas that Einstein had in the General Theory of Relativity. I feel this "theory monopoly" that Relativity has is detrimental to physics in general, being that it has

Social Welfare in Australia Essay Example

Social Welfare in Australia Essay Social Welfare in Australia Social security in Australia is a system of social welfare payments provided by the Commonwealth Government of Australia. These payments are administered by the Department of Human Services. Most benefits are subject to a means test. Payments are made to a variety of groups of people; Indigenous students and New Apprentices, age pension, assistance for isolated children (families with a child who lives a fair distance from school), carers, disability support pension, foster families, maternity payment, people who are looking for employment, parenting payment, special benefit (financial hardship) and youth allowance. 7. 1 million Australians were â€Å"customers† of Centrelink, many of which claimed from child care. The payments are paid for through general taxation. In Australia only citizens may claim these benefits. Centrelink is the agency which manages social security. Australia gives out social welfare payments to ensure more equal dispersion of wealth and to assist the lower socio-economic population. In many people’s view in Australia it is the government’s responsibility to look after the less well off, whereas in other countries, for example China, people might rely on their immediate family, for instance to look after the elderly.

In Europe, the United States and Japan, social security is financed by contributions from employers and employees, with benefits related to past earnings, therefore the higher income workers received more generous benefits if they become unemployed, disabled or retire. The rationale for Australia’s approach is that it reduces poverty more efficiently by concentrating the available resources on the poor and minimises adverse incentives. The extent to which the Australian welfare state redistributes to the poor is determined by the interactions between the tax and social security systems, both in terms of the size of taxes collected and the distribution of these taxes. This is calculated by estimating the level of spending on social security benefits as a percentage of household disposable income and then taking account of how much of this goes to the poorest fifth. The same procedure is us ed to calculate how much tax is paid by people in that group, which is then subtracted from the benefits received to give â€Å"net redistribution to the poor. †1 â€Å"The main objective of social security systems in most countries is to provide insurance against risks like unemployment, disability and sickness, and to redistribute income across the life cycle. †2 There is also the â€Å"Robin Hood† motive; take from the rich and give to the poor, which Australia is a strong example of because our system relies heavily on income testing and directs a higher share of benefits to lower income groups than any other country. Australia has the most â€Å"target efficient† system of social security benefits. Some examples of social security payments given out are: ABSTUDY is the Aboriginal and Torres Strait Islander Study Assistance Scheme and is for Indigenous Australians undergoing some form of study. All Indigenous students at secondary or tertiary institutions and primary students 14 years and older. The student must be of Aboriginal or Torres Strait Islander descent and be a current Australian citizen. The Disability Support Pension provides income support for people who suffer a long-term disability which they will not recover from in the next two years, which will determine them unable to work. The average person will receive $385. 0 monthly. The Parenting Payment is for those who are carers of dependent children under the age of 8. These customers are able to collect this payment until their youngest child turns 16. The Parenting Payment uses an individual and a partner income test to determine the rate of payment. Means and assets tests are applied to reduce the incidence of welfare fraud and contain social security spending, so as no t to â€Å"rip off† the taxpayers. In 2012-2013 the Australian Government contributed $132 million towards social security and welfare, this made up 34. % of total government expenditure. In Australia, welfare is the largest component of public spending and therefore is the main determinant of how much tax income needs to be collected.

Explore the Three Laws of Thermodynamics

Explore the Three Laws of Thermodynamics The branch of science called  thermodynamics deals with systems that are able to transfer thermal energy into at least one other form of energy (mechanical, electrical, etc.) or into work. The laws of thermodynamics were developed over the years as some of the most fundamental rules which are followed when a thermodynamic system goes through some sort of energy change. History of Thermodynamics The  history of thermodynamics  begins with  Otto von Guericke  who, in 1650, built the worlds first  vacuum pump  and demonstrated a  vacuum  using his  Magdeburg hemispheres. Guericke was driven to make a vacuum to disprove  Aristotles long-held supposition that nature abhors a vacuum. Shortly after Guericke, the English physicist and chemist  Robert Boyle  had learned of Guerickes designs and, in 1656, in coordination with English scientist  Robert Hooke, built an air pump.  Using this pump, Boyle and Hooke noticed a correlation between  pressure,  temperature, and  volume. In time,  Boyles Law  was formulated, which states that pressure and volume are  inversely proportional.   Consequences of the Laws of Thermodynamics The laws of thermodynamics tend to be fairly easy to state and understand ... so much so that its easy to underestimate the impact they have. Among other things, they put constraints on how energy can be used in the universe. It would be very hard to over-emphasize how significant this concept is. The consequences of the laws of thermodynamics touch on almost every aspect of scientific inquiry in some way. Key Concepts for Understanding the Laws of Thermodynamics To understand the laws of thermodynamics, its essential to understand some other thermodynamics concepts that relate to them. Thermodynamics Overview - an overview of the basic principles of the field of thermodynamicsHeat Energy - a basic definition of heat energyTemperature - a basic definition of temperatureIntroduction to Heat Transfer - an explanation of various heat transfer methods.Thermodynamic Processes - the laws of thermodynamics mostly apply to thermodynamic processes, when a thermodynamic system goes through some sort of energetic transfer. Development of the Laws of Thermodynamics The study of heat as a distinct form of energy began in approximately 1798 when Sir Benjamin Thompson (also known as Count Rumford), a British military engineer, noticed that heat could be generated in proportion to the amount of work done ... a fundamental concept which would ultimately become a consequence of the first law of thermodynamics. French physicist Sadi Carnot first formulated a basic principle of thermodynamics in 1824. The principles which Carnot used to define his Carnot cycle heat engine would ultimately translate into the second law of thermodynamics by the German physicist Rudolf Clausius, who is also frequently credited with the formulation of the first law of thermodynamics. Part of the reason for the rapid development of thermodynamics in the nineteenth century was the need to develop efficient steam engines during the industrial revolution. Kinetic Theory the Laws of Thermodynamics The laws of thermodynamics do not particularly concern themselves with the specific how and why of heat transfer, which makes sense for laws that were formulated before the atomic theory was fully adopted. They deal with the sum total of energy and heat transitions within a system and do not take into account the specific nature of heat transference on the atomic or molecular level. The Zeroeth Law of Thermodynamics This zeroeth law is sort of transitive property of thermal equilibrium. The transitive property of mathematics says that if A B and B C, then A C. The same is true of thermodynamic systems that are in  thermal equilibrium. One consequence of the zeroeth law is the idea that measuring  temperature  has any meaning whatsoever. In order to measure temperature,  thermal equilibrium  must be  reached between the thermometer as a whole, the mercury inside the thermometer, and the substance being measured. This, in turn, results in being able to accurately tell what the temperature of the substance is. This law was understood without being explicitly stated through much of the history of thermodynamics study, and it was only realized that it was a law in its own right at the beginning of the 20th century. It was British physicist Ralph H. Fowler who first coined the term zeroeth  law, based on a belief that it was more fundamental even than the other laws. The First Law of Thermodynamics Though this may sound complex, its really a very simple idea. If you add heat to a system, there are only two things that can be done change the  internal energy  of the system or cause the system to do work (or, of course, some combination of the two). All of the heat energy must go into doing these things. Mathematical Representation of the First Law Physicists typically use uniform conventions for representing the quantities in the first law of thermodynamics. They are: U1  (or  Ui) initial internal energy at the start of the processU2  (or  Uf) final internal energy at the end of the processdelta-U  Ã‚  U2  -  U1   Change in internal energy (used in cases where the specifics of beginning and ending internal energies are irrelevant)Q  Ã‚  heat  transferred into (Q   0) or out of (Q   0) the systemW  Ã‚  work  performed by the system (W   0) or on the system (W   0). This yields a mathematical representation of the first law which proves very useful and can be rewritten in a couple of useful ways: The analysis of a  thermodynamic process, at least within a physics classroom situation, generally involves analyzing a situation where one of these quantities is either 0 or at least controllable in a reasonable manner. For example, in an  adiabatic process, the heat transfer (Q) is equal to 0 while in an  isochoric process  the work (W) is equal to 0. The First Law Conservation of Energy The  first law  of thermodynamics is seen by many as the foundation of the concept of conservation of energy. It basically says that the energy that goes into a system cannot be lost along the way, but has to be used to do something ... in this case, either  change  internal energy or perform work. Taken in this view, the first law of thermodynamics is one of the most far-reaching scientific concepts ever discovered. The Second Law of Thermodynamics Second Law of Thermodynamics:The second law of thermodynamics is formulated in many ways, as will be addressed shortly, but is basically a law which - unlike most other laws in physics - deals not with how to do something, but rather deals entirely with placing a restriction on what can be done. It is a law that says nature constrains us from getting certain kinds of outcomes without putting a lot of work into it, and as such is also closely tied to the  concept of the conservation of energy, much as the first law of thermodynamics is. In practical applications, this law means that any  heat engine  or similar device based  on  the principles of thermodynamics cannot, even in theory, be 100% efficient. This principle was first illuminated by the French physicist and engineer Sadi Carnot, as he developed his  Carnot cycle  engine in 1824, and was later formalized  as a law of thermodynamics  by German physicist Rudolf Clausius. Entropy and the Second Law of Thermodynamics The second law of thermodynamics is perhaps the most popular outside of the realm of  physics because it is closely related to the concept of  entropy or the disorder created during a thermodynamic process. Reformulated as a statement regarding entropy, the second law reads: In any closed system, in other words, each time a system goes through a thermodynamic process, the system can never completely return to precisely the same state it was in before. This is one definition used for the  arrow of  time since entropy of the universe will always increase over time according to the second law of thermodynamics. Other Second Law Formulations A cyclic transformation whose only final result is to transform heat extracted from a source which is at the same temperature throughout into work is impossible. - Scottish physicist William Thompson ( A cyclic transformation whose only final result is to transfer heat from a body at a given temperature to a body at a higher temperature is impossible. - German physicist Rudolf Clausius All the above formulations of the Second Law of Thermodynamics are equivalent statements of the same fundamental principle. The Third Law of Thermodynamics The third law of thermodynamics is essentially a statement about the ability to create an  absolute  temperature scale, for which  absolute zero  is the point at which the internal energy of a solid is precisely 0. Various sources show the following three potential formulations of the  third law  of thermodynamics: It is impossible to reduce any system to absolute zero in a finite series of operations.The entropy of a perfect crystal of an element in its most stable form tends to zero as the temperature approaches  absolute zero.As temperature approaches absolute zero, the entropy of a system approaches a constant What the Third Law Means The third law means a few things, and again all of these formulations result in the same outcome depending upon how much you take into account: Formulation 3 contains the least restraints, merely stating that entropy goes to a constant. In fact, this constant is zero entropy (as stated in formulation 2). However, due to quantum constraints on any physical system, it will collapse into its lowest quantum state but never be able to perfectly reduce to 0 entropy, therefore it is impossible to reduce a physical system to absolute zero in a finite number of steps (which yields us formulation 1).

DuPond fibre Inc Marketing - Case Study Example Thus the technological upgradation works need to be undertaken without causing much harm to the prevailing business volumes. Further, all the management functions too need to be appropriately re-engineered to meet the future growth expectation of the company and also to retain its competitive advantage being enjoyed currently. The brief descriptions on the type of initiatives being undertaken in the various departments are explained as follows. The supporting data and the other relevant information about all the decision being presented here given separately in the Appendix. The raw materials being used in both type of the processes are the same and no significant change in the type materials procured for the process exist. But the change in volume of procurement would certainly vary occurs across the sites of production. Earlier, pattern of procurement was identical at site 1 and site 2, while the site 3 had almost three times higher rates of procurement than the earlier mentioned locations. But in the changed scenario all the locations would be having same procurement patterns after full-scale operations are in place at all the centers of production. And with increased volume requirement identification the current suppliers would be given the license of the supply and also to maintain the identical quality of materials supplied. On production sigi On production sigifinificant changes are expected. The change over of operations from the production of one type of fibre to the other need a careful planning. Both at site 1 and site 2, a new set of facilities would be installed. This might require atleast 3 to 4 years due to the process involved in approvals and installation works. In 2006, the modification to the facilities could also be initiated as the sales forecast is lesser in 2008. This process might require only 2 years. Once, site 1 modifications is completed ,site 2 works could also be initiated. Thus by 2009 , four fully functional facilities would be in operation to produce the modified fibre. The only one of the three units at the site 3 shall be changed to accommodate the new type of production process. The other two types here shall be retained for the manufacture of non-woven fibres. Sales and Marketing The major change in the marketing process is to bring a new set of customers to its modified fibre product. Though all its non-woven customers have not shifted to the newer product, it leaves a big exercise to create a new set of clients for its products (Kotler and Amstrong, 2001). The major marketing campaign involves extensive business conference that has been arranged for all the industry operators to create the importance of the modified fibre supplied by the company. The sales team would be set into operation to generate the potential sales. These exercises have a time of 4 years from now as the forecasted sales is 3 million Kg in the year 2009. With the prevailing demand for these type of fibres, the sales team would generate higher sales volume as the expected sales from this product category is 30 million Kg of fibre. Finance/ Costing Based on the forecasts presented in demand it is estimated significant investments would be required during the period from 2006 to 2009 (Beasley, n.d.). The with the total volume of sales in 2006 is reported as 24.7 million Kg of fibre. With the prices of 0.9 UD dollars for every Kg of non-woven fiibre, the
