Question

3 how does a balanced chemical equation satisfy the law of conservation of mass? a during a chemical reaction, the total amount of matter stays the same. b during a chemical reaction, matter is destroyed. c during a chemical reaction, one or more new substances are formed. d during a chemical reaction, the total number of atoms increases.

Explanation:

The Law of Conservation of Mass states that matter is neither created nor destroyed in a chemical reaction. A balanced chemical equation reflects this by having the same number of each type of atom on both sides of the equation, which means the total amount of matter remains the same. Option B is incorrect because matter is not destroyed. Option C is a correct statement about chemical reactions (new substances are formed), but it does not directly relate to how a balanced equation satisfies the Law of Conservation of Mass. Option D is incorrect as the total number of atoms does not increase in a chemical reaction.

Answer:

A. During a chemical reaction, the total amount of matter stays the same.
