Chemical reactions are classified into types to help us analyze them and also to help us predict what the products of the reaction will be. The five major types of chemical reactions are synthesis, decomposition, single replacement, double replacement, and combustion.he best way to remember a decomposition reaction is that for all reactions of this type, there is only one reactant. Notice the only reactant, NH 4 NO 3, is on the left of the arrow, but there is more than one product on the right side of the arrow.
