What does the law of conservation of mass say about chemical reaction

Question

A. Mass increases as atoms are rearranged during a chemical reaction
B. In a chemical reaction mass is neither created nor destroyed
C. Mass is not measurable in a chemical reaction
D. To balance a chemical equation additional Mass maybe created

Answer 1

The correct answer is:

B. In a chemical reaction mass is neither created nor destroyed.

The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This means that mass remains constant, and it is merely rearranged during the reaction.
