Solution. Galena is an ore of lead (Pb). Chemically it is lead sulphide ( PbS). To obtain lead (Pb) from it, galena ( PbS) is first converted into lead oxide ( PbO) by reacting it with oxygen followed by reduction of lead oxide ( PbO) by carbon (C). 2 PbS ( l) + 2 O 2 ( g) → 2 PbO ( l) + 2 SO 2 ( g) ( Lead ( Lead sulphide) oxide)
