Question

cu2s+ 2 cu2o --->6 cu +so2 the above process is​

Answer 1

This process is doble displacement reaction

Answer 2

Answer: Self Reduction

Explanation:

During the Bessemerisation process, the sulphide ores of less electropositive metals are heated in air to convert part of the ore into oxide or sulphate which then react with the remaining sulphide ore to give the metal and sulphur dioxide.

Copper sulphide is partially oxidised to cuprous oxide which further can react with remaining copper sulphide to form copper and sulphur dioxide.

2Cu2

S + 3O

2  → 2Cu2  O+ 2SO2

​

Cu2S + 2Cu2O → 6Cu + SO2

This process is also called  autoreduction process or air reduction process.
