Different proportions of oxygen in the various oxides of nitrogen prove the

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:

Choose the incorrect statement about Dalton's Atomic Theory.

The statement related to the law of definite proportions is:

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:
