What does the Law of Conservation of Mass state?
Mass is always conserved in chemical reactions.
The mass of the products in a chemical reaction is always equal to the mass of the reactants.
Mass can be created or destroyed in a chemical reaction.
The mass of the reactants in a chemical reaction is always more than the mass of the products.
Explanation
The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction; therefore, the mass of reactants equals the mass of products.
