The breaking down of one reactant into two or more components is called

Explanation:
In a decomposition reaction, a single compound breaks apart into two or more simpler substances. This matches the idea of one reactant breaking down into multiple components. For example, hydrogen peroxide splits into water and oxygen gas: H2O2 → H2O + O2. The other types don’t describe this process: synthesis is when two or more substances combine to form one product, double-replacement involves exchange of ions between two compounds to make new substances, and combustion is burning a fuel with oxygen to yield products like carbon dioxide and water.
