    Mass cannot be created nor destroyed - it is only converted into other things. All the mass that exists now has existed and will exist in the same quantity forever, but it changes forms like liquid to solid or solid to gas or gas to liquid. Another example would be taking two things and creating one thing with it

    2H2 + O2 = 2H2O

    Mass is conserved even though we took two things and created one thing with it. The product (water) is the same as the two reagents hydrogen and oxygen.

    The Law of Conservation of Mass states that the mass of the products in a reaction is equal to the mass of the reactants in the equation.

    Matter is neither created nor destroyed, only converted.
