Question

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

Explanation:

The Law of Conservation of Mass states that matter is neither created nor destroyed in a chemical reaction. A balanced chemical equation has the same number of each type of atom on both sides of the equation. This means that the total amount of matter (atoms) remains constant. Option A is about formation of new substances (not directly about mass conservation). Option B is incorrect as matter is not destroyed. Option C is wrong as the total number of atoms does not increase. Option D aligns with the Law of Conservation of Mass.

Answer:

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