Why SO3, SO2 & O2 does not obey the Law Of Reciprocal Proportions? Are these the only which does not obey this law?

Expert Answer
According to the law, If the two elements combine separately with a third element, the mass ratio of the first two elements combined with a fixed mass of the third element will be equal to or in simple ratio to the mass ratio of first two elements in a compound formed by their direct combination..
In other words, the mass of several elements A, B, C which combine separatley witha a fixed mass of another element D are the same as or simple multiples of the masses in which A, B, C themselves combine with one another.
Law of reciprocal proportions for SO3, SO2 & O2 is given by,
SO3 → 32 : 48 = 2 : 3
SO2 → 32 : 32 = 1 : 1
O2 → 32
(O2 is not a compound.)
Thus, it does not obey the law of Reciprocal Proportions.
