Differences Between Ionic and Covalent Compounds Abstract In chemistry‚ a compound is a substance formed from two or more elements‚ with a fixed ratio determining the composition. A defining characteristic of a compound is that it has a chemical formula. Formulas describe the ratio of numbers of atoms in a substance. Compounds may have a number of possible phases. For a compound to be a liquid or a gas and still be called a compound‚ atoms from the various elements must be stuck together in

Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf

The Five Major Compounds That Make Up the Human Body The human body is one of the most complex and fascinating things on this planet. There are five major groups of compounds that compose the human body. These are carbohydrates‚ lipids‚ proteins‚ nucleotides‚ and water. These compounds are all very important to humans and without them humans would not be able to survive. Compounds have many functions that encourage a human cell and a human body to function. Compounds are pure substances

Communism vs. Capitalism In the political tract the Communist Manifesto‚ Karl Marx describes communism as the party that "fights for the interests of the working class" while capitalists are considered "dependent and have no individuality -- only capital is dependent and has individuality". Both of Marx’s statements are true in nature but when the two economic systems are put in practice‚ they quickly disintegrate into the same end result today‚ that is to say that most communistic nations

chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds were mixed together by the
