Question

Sulphur react with oxygen to from so2 and so3 (a) what is the law behind this​

Answer 1

• Different proportions of oxygen in the various oxides of sulphur prove the law of multiple proportions.

• This is because the ratio of masses of oxygen that combine with the same mass of sulphur (to form SO 2 and SO 3 ) is 2:3, a simple ratio.Thus, the formation and SO 3 illustrates the law of multiple proportions.
