Although countless chemical reactions exist, nearly all of them can be classified into a few specific categories. In this experiment, you will learn to differentiate five general types of chemical reactions. Some of the reactions you will perform; others will be demonstrated by your teacher. From observations, you will identify the products of each reaction and determine the type of reaction that has taken place. You will consider the following reaction types: combination reactions, decomposition reactions, single-replacement, double-replacement reactions, and combustion reactions. The majority of common chemical reactions can be classified as belonging to one of these categories.
