Question

Answer 1

Concept:

Law of multiple proportions:

When two or more compounds are formed by the combination of two elements, the weight of one element that combines with the other is in simple ratios of whole numbers.
It was formulated by Dalton.

Law of reciprocal proportion:

When two different elements combine with the same mass of a third element, then their masses are either same or in a simple ratio of whole numbers.
When hydrogen and oxygen combine with Carbon to form CH4 and CO2 respectively, their masses are in a ratio 1: 8.

Law of conservation of mass:

Mass in an isolated system can neither be created nor destroyed.
During a chemical process, the mass of the elements is the same as before after the reaction.

Explanation:

The five oxides of Nitrogen and the weight ratio of the elements are:

When oxides of nitrogen are formed with oxygen, the masses of oxygen are 8g,16g, 24g, 32g, 40etc. the ratio is 1: 2 : 3: 4: 5.

Hence, the formation of five oxides of nitrogen is an example of the Law of multiple proportions.
