Cu ==> Cu^2+ + 2e
H2SO4 + 2H^+ + 2e ==> SO2 + 2H2O
---------------------------------
Add the two half equations and cancel anything common to both sides. Finally, add extra sulfate ions, if needed to form CuSO4 on the right. I shall be happy to look at your final answer.
Write a balanced net ionic equation for the oxidation of metallic copper to Cu(II) ion by hot concentrated H2SO4, in which the sulfur is reduced to SO2
