Which sentence is a statement of the law of conservation of mass?
O A. In a chemical reaction, mass remains the same, even though the
types of atoms can change.
B. In a chemical reaction, the mass per volume of the reactants
equals the mass per volume of the products.
C. In a chemical reaction, atoms can be rearranged, but the total
mass of each type of atom never changes.
O D. In a chemical reaction, mass is conserved, but the numbers and
types of atoms are not.

Answer:

C

Explanation:

The law of conservation of mass states that the added mass of the reactants is equal to the added mass of the products.

A cannot be because it says that for example if you have two hydrogens in the reactants, those two hydrogens transform in for example 2 oxygen and the hydrogen disappear. that's impossible in chemistry.

B. Volume does not directly deal with that law of conservation of mass

C. Is correct, you can rearrange the atoms but if you keep the same amount of mass for each atom and you do not omit any atom, you are respecting the law of conservation of matter.

D.Same explanation for A
