Iron forms two oxides, in first oxide `56` grams. Iron is found to be combined with `16` grams oxygen and in second oxide `112` grams iron is found to be combined with `48` grams oxygen. This data satisfy the law of

Nitrogen and oxygen combine to form many oxides. In some oxides, 14 g of nitrogen combine with either 16 g of oxygen or 32 g of oxygen. In some other oxides, 28 g of nitrogen combine with 16, 48, or 80 g of oxygen, (i) What are the formulae of the oxides ? (ii) What law of chemical combination does the formation of these compounds illustrate ?

Oxygen combines with iron found in the rocks to form:
