What are the original substances present before a chemical reaction takes place called?

Explanation:
Starting materials are the substances you begin with in a chemical change. These are called reactants, the ones that undergo transformation to form new substances. In a chemical equation, you see reactants on the left and products on the right. Intermediates are short‑lived species formed during the process, not the starting materials. Catalysts speed up the reaction without being consumed, so they aren’t the original substances you start with. So the original substances present before a chemical reaction take place are reactants.
