Explain the following in terms of gain or loss of oxygen with two examples each . (a) Oxidation (b) Reduction |
|
Answer» Solution :Oxidation REACTION : It is a chemical reaction in which gain of oxygen or loss of hydrogen takes place ,br> (1) `2Mg(s)+O_(2)(g) OVERSET("heat") to 2MgO(s)` Here, MAGNESIUM is oxidised to become Magnesium OXIDE. (2) `2Cu(s)+O_(2)(g) overset("heat") to 2CuO(s)` Here, copper is oxidised to become copper oxide. Reduction reaction : It is chemical reaction in which loss of oxygen or gain of hydrogen takes place. (1) `CuO+H_(2) overset("Heat") to Cu+H_(2)O` here, copper oxide is reduced to become copper. `ZnO+C overset("Heat") to Zn +CO`, here zinc oxide is reduced to become Zinc. |
