Answer 1

Hello mate good morning. I have an answer to your given question.

question : 21. What happens when copper turnings  are added to sulphuric acid and heated?​

Answer: when copper is heated with conc.H2SO4, a redox reaction occurs and the acid gets reduced to sulphur dioxide.

Cu + 2H2SO4 ⇒CuSO4 + SO2 + 2H2O.
