Question

what does the law of conservation of mass state about chemical reactions? * 1 point the law of conservation of mass states that the number of molecules must always increase. the law of conservation of mass states that only gases are conserved in a chemical reaction. the law of conservation of mass states that energy is always lost during a chemical reaction. the law of conservation of mass states that atoms are neither created nor destroyed in a chemical reaction.

Explanation:

The law of conservation of mass in chemistry states that in a chemical reaction, the total mass of the reactants equals the total mass of the products. This is because atoms are conserved - they are neither created nor destroyed during the reaction. The other options mis - state the law. The number of molecules can change, not all gases are conserved in a special way compared to other substances, and the law of conservation of mass is about mass, not energy loss in a reaction.

Answer:

The law of conservation of mass states that atoms are neither created nor destroyed in a chemical reaction.
