Vedclass · Answer

(C) The Law of Multiple Proportions states that when two elements combine to form more than one compound,the masses of one element that combine with a fixed mass of the other are in the ratio of small whole numbers.In the pair $CuO$ and $Cu_2O$:$1$. Both compounds are formed by the same two elements: Copper $(Cu)$ and Oxygen $(O)$.$2$. In $CuO$,$63.5 \ g$ of $Cu$ combines with $16 \ g$ of $O$.$3$. In $Cu_2O$,$127 \ g$ of $Cu$ $(2 	imes 63.5)$ combines with $16 \ g$ of $O$.$4$. For a fixed mass of $O$ $(16 \ g)$,the ratio of the masses of $Cu$ is $63.5 : 127$,which simplifies to $1 : 2$,a simple whole number ratio.Therefore,$CuO$ and $Cu_2O$ follow the Law of Multiple Proportions.

Cupric Carbonate	% of $Cu$	% of $C$	% of $O$
Natural sample	$51.35$	$9.74$	$38.91$
Synthetic sample	$51.35$	$9.74$	$38.91$

Which of the following pairs of substances illustrates the Law of Multiple Proportions?
