Separation of Mixtures 9/11/11 * Introduction: A compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Unlike a compound‚ a mixture is a material system made up by two or more different substances which are mixed together but are not combined chemically. There are two kinds of mixtures‚ homogeneous and heterogeneous. Homogeneous mixtures have the same composition and appearance throughout

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

when compared to traditional methods. Synthesis of organometallic compounds usually requires long time at elevated temperatures and these reaction conditions are optimal to exploit microwave assisted synthesis. The target compounds are the three classes of Organo-iron complexes which are sandwich complexes‚ cyclopentadienyl carbonyl complexes and phosphine tricarbonyl complexes. Several compounds from these classes were studied and it was found that refluxing time was reduced to

body. A medicine is often a mixture of several chemical compounds. Even if it has only one active component compound often other substances are used as fillers or binders to give it bulk. Chemistry‚ the science related to chemical substances‚ provides us the tools to make and study the substances that are the constituents of almost all medicines. The past hundred years or so‚ ever since the advent of organic chemistry‚ many chemical compounds have been discovered in nature that are effective for curing

College Algebra Project Saving for the Future In this project you will investigate compound interest‚ specifically how it applies to the typical retirement plan. For instance‚ many retirement plans deduct a set amount out of an employee’s paycheck. Thus‚ each year you would invest an additional amount on top of all previous investments including all previously earned interest. If you invest P dollars every year for t years in an account with an interest rate of r (expressed as a decimal) compounded

Joe Luong 230105559 Chem 250 L2 Oct‚4‚2012 Introduction: Extraction is the experimental procedure of obtaining a desired compound with the use of a solvent from either a liquid or solid mixture. Solid-liquid extraction involves the removal of organic compounds from solid material. This method of extraction may be achieved through extraction of the organic compound at the boiling point of a polar solvent such as water. Using water as the solvent will typically result in a 61-85 percent extraction
