It states that when two different elements separately combine with the fixed mass of a third element, the proportion in which they combine with one another shall be either in the same ratio or some simple multiple of it.
In CH4 and H2O the ratio of the masses of carbon and oxygen that combine with a fixed mass of hydrogen is 3 : 8.
Now, when C and O combine with each other to form carbon dioxide (CO2), they do so in the same proportion, i.e. 12 : 32 = 3 : 8 parts by mass.
Hence, they illustrate the law of reciprocal proportions.
