The correct statement is:
**It is balanced because the mass of the reactants equals the mass of the products.**
In a balanced chemical equation, the number of atoms of each element is the same on both sides of the equation, which ensures that the mass is conserved during the reaction.
**It is balanced because the mass of the reactants equals the mass of the products.**
