Answer 1

Answer:

Atoms of the reactant(s) must equal the atoms of the product(s).

Explanation:

According to the Law of Conservation, all atoms of the reactant(s) must equal the atoms of the product(s).

As a result, we need to balance chemical equations. We do this by adding in coefficients to the reactants and/or products. The compound(s) itself/themselves DOES NOT CHANGE.
