Question

during a chemical reaction, the law of states that the total mass of the products must be equal to the total mass of the reactant. a multiple proportions b definite proportions c conservation of mass

Explanation:

The law of conservation of mass in chemistry states that mass is neither created nor destroyed in a chemical reaction. So, the total mass of products equals the total mass of reactants. The law of multiple proportions (a) deals with elements combining in multiple ratios. The law of definite proportions (b) states a compound has a fixed ratio of elements by mass. Thus, c is correct.

Answer:

C. Conservation of mass
