Vedclass · Answer

(A) According to the Law of Multiple Proportions,when two elements combine with each other to form two or more than two compounds,the masses of one of the elements that combine with a fixed mass of the other bear a simple whole number ratio.In $CO$,$12$ parts by mass of carbon combine with $16$ parts by mass of oxygen.In $CO_2$,$12$ parts by mass of carbon combine with $32$ parts by mass of oxygen.The ratio of masses of oxygen that combine with a fixed mass of carbon $(12 \ g)$ in these compounds is $16:32$ or $1:2$,which is a simple whole number ratio.This confirms the Law of Multiple Proportions.

Carbon and oxygen combine to form two oxides,carbon monoxide and carbon dioxide,in which the ratio of the weights of carbon and oxygen is respectively $12 : 16$ and $12 : 32$. These figures illustrate the:
