iron ore equations

Carbon is more reactive thaniron, so it can push out or displace theironfromironoxide. Here are theequationsfor the reaction:ironoxide + carbon →iron+ carbon dioxide 2Fe 2 O 3 + 3C → 4Fe + 3CO 2 In this reaction, theironoxide is reduced toiron, and the carbon is oxidised to carbon dioxide.
