What are the substances written on the left side of the arrow in a chemical equation called?

Answer and explanation

Correct answer: Reactants

The governing concept is the standard structure of a chemical equation. The substances written on the left side of the reaction arrow are the starting materials that undergo chemical change, so they are called reactants. The substances formed on the right side are products. A catalyst may speed up a reaction without being consumed, and a solvent is the medium in which a reaction may occur; neither term names all substances on the left. Therefore, option B is correct.
