    CH4 + 2O2 ==> CO2 +2H2O + heat

    This is a combustion reaction; also an oxidation-reduction equation.
    For #4, add up the molar masses on each side and see if they match.
    You have 16 for CH4 and 64 for 2O2 for a total of 80 grams.
    What do you have on the right? Does that prove the law of conservation of mass?
