BACKGROUND A chemical reaction is a process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of substances. An example of a chemical reaction is formation of rust (iron oxide), which is produced when oxygen in the air reacts with iron. The products obtained from a given set of reactants, or starting materials, depend on the conditions under which a chemical reaction occurs.
