When wood is in the presence of oxygen, it burns and releases CO2 and H2O. Compare the mass of wood and oxygen before it burns to the carbon dioxide, water, and ash that results.
the total mass will be less
the total mass will be greater
the total mass should be the same due to the Law of Conservation of Mass.
If a chemical reaction occurs and the mass of the product is not the same as the mass of the reactants, what has happened?
The Law of Conservation of Mass has been broken.
The reaction produced a gas that was not contained in a closed system.
