In this case, the change in chemical and physical properties resulting from the interaction of the hydroxyl and carbonyl group are so profound that the combination is customarily treated as a distinct and different functional group. 1. Nomenclature of Carboxylic Acids. As with aldehydes, the carboxyl group must be located at the end of a carbon ... Chemical reactions are often classified into the five categories listed on the left panel. Lab 4 focused on physical and chemical changes. The chemical changes included decomposition, oxidation, and double replacement reactions. The previous lab (Lab 8) focused solely on single replacement reactions. http://www.glencoe.com/sites/common_assets/science/virtual_labs/E19/E19.swf In this lab, with the use of indicators as chemical detection tools, you will analyze a variety of foods for the presence of nutrients. Detection is based upon observing a chemical change that takes place most often a change in color.
