Carbon and $CO$ gas are used to reduce which of the following pairs of metal oxides for extraction of metals ?

$FeO,\,SnO$

$SnO,\,ZnO$

$BaO,\,Na_2O_2$

$FeO,\,ZnO$

(AIIMS-2007)

Solution

$ZnO + C \to Zn + CO$

$FeO + C \to Fe + CO$

In the process of smelting the oxide ore is reduced by carbon and the metal may be obtained in the molten state or as vapours which are condensed. Metals like $Zn,\,Fe,\,Pb$ or $Sn$ are obtained by this process.
