Question

Set of compounds that can illusrate law of multiple proportion is
1)H,O, H,S
2) H,O, H,02 3) CO, H,O
4) CH4, H,O, CO2​

Answer 1

Explanation:

The following pairs of compounds illustrate the law of multiple proportions:

SO

2

and SO

3

NO

2

and N

2

O

NO and N

2

O

5

According to the law of multiple proportions, if two elements chemically combine with each other forming two or more compounds, with different compositions by mass then the ratios of masses of two interacting elements in the two compounds are small whole numbers.

Consider the example SO

2

and SO

3

For SO

2

32 g sulphur

32 g oxygen

= 1

For SO

3

32 g sulphur

48 g oxygen

= 1.5

The two ratios are in proportion

1.5
