Question

find the ratios of oxygen in nitrogen compounds,N2O,NO,N2O3,N2O4,N2O5 using law of multiple proportions?

Answer 1

Answer:

hello this is nikhil

glad to help you!

Explanation:

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

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".

Example.

14 g of nitrogen combine with 16  g of oxygen to form 30 g of NO.

The ratio of masses N:O is 14:16.

14 g of nitrogen combine with 32  g of oxygen to form 46 g of NO

.

The ratio of masses N:O is 14:32.

The two ratios are in the proportion of 32:16=2:1
