balance chemical reaction of extraction of iron from iron ore
Extraction of iron on a match head
Iron (III) oxide + carbon → iron + carbon dioxide 2Fe 2 O 3 (s) + 3C (s) → 4Fe (s) + 3CO 2 (g) Carbon is more reactive than iron. The iron oxide is reduced by the carbon (the oxygen is removed) to form metallic iron. The sodium carbonate fuses easily and brings the iron oxide into close contact with the carbon.

For example, in the rusting of iron, the oxidation state of iron atoms increases as it converts to an oxide and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. [4]
