Answer 1

The answer is c. Matter cannot be created or destroyed in a chemical reaction.

Answer 2

The correct answer is C) Matter cannot be created or destroyed in a chemical reaction. The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products, meaning that matter cannot be created or destroyed. This law is a fundamental principle in chemistry and is important for balancing chemical equations.
