11. Which is another way of saying the law of conservation of mass? Matter cannot be created or destroyed.
The mass of the reactants always equals the mass of the products,
the law of conservation of matter
all of the above

all of the above

Explanation:

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

The Law of Conservation of Matter states that matter can change form through physical and chemical changes but matter is conserved. The same amount exists before and after the change. Matter is not created or destroyed.

So the answer will be all of the above.
