可能你抄錯了，這方程式不可能平衡。
其他類近的答案包括：
(1) Cu + 2H2SO4 → CuSO4 + 2H2O + SO2
(2) Cu + H2SO4 → CuSO4 + H2 (但該反應不可能進行。)

Your eqt. is wrong.
Hot concentrated H2SO4 attacks all metals (except gold and platinum), forming the corresponding sulphate and sulphur dioxide (gas).
Cu + 2H2SO4 —＞ CuSO4 + SO2 + 2H2O
It is due to the oxidizing property of concentrated H2SO4.

If you mean mix it , it is (H2SO4)2CU
IF YOU MEAN WHAT did he add , then the answer is he add one O .
