Question

what does the law of conservation of mass say about a chemical reaction? (1 point)
in a chemical reaction, mass is neither created nor destroyed
mass increases as atoms are rearranged during a chemical reaction
mass is not measurable in a chemical reaction.
to balance a chemical equation, additional mass may be created

Explanation:

The Law of Conservation of Mass states that in a chemical reaction, the total mass of the reactants equals the total mass of the products. Mass is conserved, meaning it is neither created nor destroyed.

Answer:

In a chemical reaction, mass is neither created nor destroyed
