Final answer:
A chemical equation is a statement that uses chemical formulas to show the identities and relative amounts of substances involved in a chemical reaction.
Step-by-step explanation:
A statement that uses chemical formulas to show the identities and relative amounts of the substances involved in a chemical reaction is called a chemical equation.
A chemical equation consists of reactants on the left side, separated by an arrow from products on the right side. Coefficients are used to represent the relative amounts of each substance involved in the reaction. The balanced chemical equation ensures that the number of atoms and the total charge are the same on both sides of the equation.
