Question

Which law of chemical combination can be illustrated by taking the
compositionof SO2, and SO3 taken together?​

Answer 1

Answer:

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 of SO  

2

​  

 and SO  

3

​  

 illustrates the law of multiple proportions.
