Question

CO and CO2 can be considered, as an example for law of multiple proportion.

a. Illustrate the same law by using the oxides of a metal containing 78.7% and

64.5% of the metal​

Answer 1

Explanation:

There are compounds made up of the same elements, like carbon monoxide (CO) and carbon dioxide (CO2). Both compounds are made of carbon (C) atoms and oxygen (O) atoms; however, the ratios of carbon and oxygen in each compound is different. This illustrates the law of multiple proportions.

Answer 2

Law of Multiple proportion states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers.

For example let us assume 2 molecules CO(carbon monoxide) adn CO2(carbon dioxide).

CO= 12gm of carbon + 16 gram of Oxygen.

CO2= 12gm carbon+ 32 gram of Oxygen .

thus ratio of mass of oxygen in the given two compounds is 16:32=1:2.

thus law of multiple proportions is proved.
