Problem

In the extraction of copper, metal is formed in the Bessemer converter due to the reaction : (1)

2\text{Cu}_2\text{O} \longrightarrow 4\text{Cu} + \text{O}_2

(2)

2\text{CuO} + \text{CuS} \longrightarrow 3\text{Cu} + \text{SO}_2

(3)

\text{Cu}_2\text{S} + 2\text{Cu}_2\text{O} \longrightarrow 6\text{Cu} + \text{SO}_2

(4)

\text{Fe} + \text{Cu}_2\text{O} \longrightarrow \text{FeO} + 2\text{Cu}
