Problem

Formation of metallic copper from the sulphide ore in the commercial metallurgical process involves. (1)

Cu_2S + \frac{3}{2}O_2 \longrightarrow Cu_2O + SO_2

;

Cu_2O + C \longrightarrow 2Cu + CO

(2)

Cu_2S + \frac{3}{2}O_2 \longrightarrow Cu_2O + SO_2

;

2Cu_2O + Cu_2S \longrightarrow 6Cu + SO_2

(3)

Cu_2S + 2O_2 \longrightarrow CuSO_4

;

CuSO_4 + Cu_2S \longrightarrow 3Cu + 2SO_2

(4)

Cu_2S + \frac{3}{2}O_2 \longrightarrow Cu_2O + SO_2

;

Cu_2O + CO \longrightarrow 2Cu + CO_2
