Economics Revision AER (saving) Annual Equivalent Rate (AER) shows the percentage of compound interest that would be paid on your savings once a year if you didn’t withdraw or add anything. The AER is the official rate for savings accounts‚ and allows you to compare rates fairly. You might also see the ‘Gross’ interest rate shown – which will be less than the AER because it doesn’t show compound interest‚ just the flat rate of interest you’d get for the original amount you saved.

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
