Reduction of $2.4 \ g$ of $FeO$ with hydrogen yields $1.68 \ g$ of $Fe$. In another experiment,$2.9 \ g$ of $FeO$ on reduction with hydrogen yields $2.03 \ g$ of $Fe$. These results illustrate the law of:

According to Dalton's atomic theory,atoms of an element are

The percentage of copper and oxygen in samples of $CuO$ obtained by different methods were found to be the same. This illustrates the law of

$2 \ g$ of hydrogen combine with $16 \ g$ of oxygen to form water and with $6 \ g$ of carbon to form methane. In carbon dioxide,$12 \ g$ of carbon are combined with $32 \ g$ of oxygen. These figures illustrate the law of:
