Question

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

(a) equivalent proportion

(b) multiple proportion

(c) constant proportion

(d) conservation of matter

Answer 1

Correct option is (b) multiple proportion

As per the law of multiple proportions, when two elements combine to form two or more compounds, the ratios of the masses of two interacting elements in the two compounds are small whole numbers.

Thus, different proportions of oxygen in the various oxides of nitrogen prove the law of multiple proportion.
