Balancing a chemical equation is based on which law?

Answer and explanation

Correct answer: Law of conservation of mass

According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction. Therefore, a balanced equation has the same number of atoms of each element on the reactant and product sides, so total mass is conserved. The law of conservation of energy also applies to reactions, but balancing an equation specifically requires equal numbers of atoms.
