Predicting and Explaining an Example of Chemical Change in decomposition. 1. Write your own explanation for what chemical changes are involved in this process. Students should be able to tell a coherent story at this point, drawing from previous lessons. 2. Predict what happens to the masses of materials involved in this process.

Substances may be created by chemical change and may also undergo chemical change. If a substance is produced as a result of a chemical change, or reaction, it is called a product. If a substance is the subject of a chemical change, it is a reactant. Any substance can be either a reactant or product, depending on the chemical reaction.

A decomposition reaction, as you can guess, is the opposite of a combination reaction. This is a chemical change in which a single compound breaks down into two or more products (AB = A + B). Most decomposition reactions require energy in the form of heat or light.
