Question

Different proportions of oxygen in the various oxides of nitrogen prove the law of:
Conservation of mass
(B) Multiple proportion
(C) Constant proportion
Definite proportion​

Answer 1

Answer:

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.

Explanation:

The relation or adaptation of one portion to another, or to the whole, as respect magnitude, quantity, or degree; comparative relation; ratio; as, the proportion of the parts of a building, or of the body.
