Help with law of multiple proportions.

Chemistry Question (Law of Mult. Proportions): Relatively simple but I'm missing the point...?

  • Answer:

    H2O and H2O2 this is one of those silly laws from the time of Priestly and Dalton where they determined that a set of elements can combine in multiple proportions. It seems rather obvious now, but it wasn't back then.

choice C, "When two elements combine to make more than one compound, they do so in small whole number ratios. as H2O and H2O2 It also works by mass In H2O the mass of H2=2 and the mass of O = l6 and in H2O2 the mass of H2 is 2 and the mass of O2 = 32 and the ratio between mass oxygen in water and in hydrogen peroxide is one to two. Other examples would be CO and CO2, SO2 and SO3, MnO and MnO2
