Question

Responses
A The mass of the reactants equals the mass of the products.The mass of the reactants equals the mass of the products.
B The mass of the reactants is less than the mass of the products.The mass of the reactants is less than the mass of the products.
C The mass of the products is always greater than the mass of the reactants.The mass of the products is always greater than the mass of the reactants.
D The mass of the reactants is greater than the mass of the products; some mass is lost when atoms recombine.The mass of the reactants is greater than the mass of the products; some mass is lost when atoms recombine.

Answer 1

A. The mass of the reactants equals the mass of the products.

According to the Law of Conservation of Matter, matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants before the reaction must equal the total mass of the products after the reaction.
