Answer the following question:
In the extraction of copper, what happens when copper(I) oxide reacts with copper(I) sulphide during heating? Explain with reference to the reaction.
When a mixture of copper(I) oxide (\(Cu_2O\)) and copper(I) sulphide (\(Cu_2S\)) is heated, it produces and .
The balanced chemical equation is \(2Cu_2O(s) + Cu_2S(s) → X\)
Where, 'X' is
