Which occurs in a chemical reaction due to the Law of Conservation of Mass?

• The mass of atoms do not change, and the atoms cannot form new arrangements.

• The reaction causes the creation of atoms and an increase in total mass.

• The mass of atoms do not change even if the atoms form new arrangements.

• The reaction causes the destruction of atoms and a decrease in total mass.
