Question

law of multiple proportion is valid for ch4 and co3 ,h2 and h2o, co and co2, h2 and o2​

Answer 1

Explanation:

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) and CO2(carbon dioxide).

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

CO2= 12gm carbon+ 32 grams of Oxygen.

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

Thus law of multiple proportions is proved.

Answer 2

Ans:- CO & CO2

Because CO is carbon monoxide & CO2 is carbon dioxide
