Answer (1)

A chemical equation is balanced by (C) adding coefficients.A chemical equation is balanced by making sure that the number of atoms of each element is the same on both sides of the equation.Coefficients are the numbers placed in front of compounds or elements in a chemical equation. They tell you how many molecules or atoms are involved in the reaction.You do not change the subscripts (the small numbers in a formula), erase elements, or add elements. Doing so would change the substances involved in the reaction.
