What is a chemical reaction equation?

A chemical reaction equation is a representation of a chemical process that shows the reactants and products of the reaction using chemical formulas and symbols. It communicates details about the reacting components and the chemical transformations that take place.

Reactants are shown on the left side of the arrow and products are shown on the right, with coefficients denoting the proportions of each material.
