What does the Law of Conservation of Mass state?

Question

A) The total mass of reactants prior to a chemical reaction is greater than the mass of the product due to the release of energy.
B) Matter cannot be rearranged during a chemical reaction.
C) The total mass of all of the reactants prior to a chemical reaction must equal the total mass of all the products after the reaction.
D) Matter is neither created or destroyed in a chemical reaction, only rearranged.

Answer 1

The correct answer is: C) The total mass of all of the reactants prior to a chemical reaction must equal the total mass of all the products after the reaction.

This statement aligns with the Law of Conservation of Mass, which asserts that mass is conserved in a chemical reaction, meaning that the mass of the substances involved must remain constant throughout the reaction.
