(A) When copper $(Cu)$ is heated with concentrated sulphuric acid $(H_2SO_4)$,it acts as an oxidizing agent and oxidizes copper to copper$(II)$ sulphate,while itself being reduced to sulphur dioxide $(SO_2)$.The balanced chemical equation is:$Cu(s) + 2H_2SO_4(conc.) \to CuSO_4(aq) + 2H_2O(l) + SO_2(g)$
