Hydrogen peroxide is a liquid people mix with water and use to disinfect skin wounds. Under certain conditions, the hydrogen peroxide molecule will break down and form water and oxygen. Look at the diagram showing before and after the molecule breaks down. What evidence supports that mass is conserved during this chemical reaction? Choose two that apply.

Amixture with the same composition throughout is!
