Question

what happens to matter during a chemical reaction according to the law of conservation of mass?
a. matter is conserved.
b. matter is created.
c. matter is converted to energy.
d. matter is destroyed.

Explanation:

The Law of Conservation of Mass states that in a chemical reaction, matter is neither created nor destroyed. It is conserved, meaning the total mass of the reactants equals the total mass of the products. The conversion of matter to energy is described by Einstein's mass - energy equivalence (E = mc²) and is not part of the Law of Conservation of Mass.

Answer:

A. Matter is conserved.
