The law of conservation of mass tells us, in part, that matter is neither created nor destroyed.

How can the law of conservation of mass for a chemical reaction be expressed?

These are the actualy answer choices

A. By using using coefficients coefficients in in a a chemical chemical equationequation

B. By writing writing a a balanced balanced chemical chemical equationequationBy

C. By counting counting the the atoms atoms present present on on each each side side of of the the equationequationAll

D. All of of the the above'

The answer is all of the above

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
