Question

a balanced equation is where the

the number of atoms of each type of element are equal both before and after the chemical reaction

the number of atoms of each type of element are not equal both before and after the chemical reaction

Explanation:

A balanced chemical equation follows the law of conservation of mass. This law states that matter is neither created nor destroyed in a chemical reaction. So, the number of atoms of each element must be the same on both sides (before and after the reaction) of the equation.

Answer:

The number of atoms of each type of element are equal both before and after the chemical reaction.
