In $SO_2$ and $SO_3$,the masses of oxygen that combine with $48 \, g$ of sulfur are respectively ......... .

When $2.16 \ g$ of metallic copper is treated with nitric acid,the weight of copper oxide obtained is $2.70 \ g$. In a second experiment,$1.15 \ g$ of copper oxide on reduction gives $0.92 \ g$ of copper. These results illustrate the law of:

Complete combustion of $0.66 \ g$ of a hydrocarbon gives $1.32 \ g$ of $CO_2$ and $2.7 \ g$ of water. The results of the given data follow the law of ...

Two compounds are formed by carbon and oxygen. In one compound,the percentage of carbon is $42.9\%$ and in the other,the percentage of carbon is $27.3\%$. Which law of chemical combination is illustrated by this data?

One part of an element $A$ combines with two parts of another element $B$. Six parts of the element $C$ combine with four parts of the element $B$. If $A$ and $C$ combine together,the ratio of their weights will be governed by
