The Law of Conservation of mass states….
During a chemical reaction, the total mass of the reactants is equal to the total mass of the products, because atoms cannot be created or destroyed, they are just rearranged.
How do you determine the state of a molecular compound?
Learn through life experience, If you don’t know a molecular compound, ask, yes even on a test!
