A chemical reaction is a process that always results in the interconversion of chemical substances. There are five kinds of chemical reactions. They are synthesis, decomposition, combustion, single-displacement, and double-displacement. Synthesis is when two or more elements or compounds combine to form a more complex compound or product. Decomposition is when compounds or elements are broken down into simpler elements or compounds. Combustion occurs when an element or compound combines with oxygen to create a large amount of heat or light. Single-Displacement is when an element is substituted out of a compound by a more reactive element. Double-Displacement is when two compounds switch ions to create two new compounds.
