How are the following metallic oxides reduced. Write equations :
(a) Iron (II) oxide
(b) Zinc oxide
(a) Iron (II) oxide is reduced by CO:
FeO+CO→ΔFe+CO2[g]\text{FeO} + \text{CO} \xrightarrow{\Delta} \text{Fe} + \text{CO}_{2} [\text{g}]FeO+COΔFe+CO2[g]
(b) Zinc oxide is reduced by coke :
ZnO+C→1400°CZn+CO[g]\text{ZnO} + \text{C} \xrightarrow{1400 \degree\text{C}} \text{Zn} + \text{CO} [\text{g}]ZnO+C1400°CZn+CO[g]
