Question

which best describes a chemical reaction applying the law of conservation of mass? an equation which does not use energy an unbalanced equation in which the reactants and products are unequal a balanced equation in which the reactants and products equal an equation which uses energy

Explanation:

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. A balanced chemical equation has equal numbers of each type of atom on both the reactant and product sides, which means the mass of reactants equals the mass of products. An unbalanced equation violates this law as reactants and products would have unequal masses. Whether an equation uses energy or not is not related to the Law of Conservation of Mass.

Answer:

C. a balanced equation in which the reactants and products equal
