Question

Cu+H3SO4→Mg+H2SO4→CuO+Al→Cu+ZnCl2→Zn+CuSO4→

Answer 1

Mg+H2SO4(p)→MgSO4+H2
3CuO+2Al→3Cu+Al2O3
Cu+ZnCl2→реакция не идет
Zn+CuSO4→ZnSO4+Cu

Answer 2

It seems like you've provided a series of chemical reactions, but they are not balanced or fully specified. I'll do my best to help you balance and clarify these reactions:

1. Cu + H2SO4 → ? (This reaction is not specified, and the products are missing.)
2. Mg + H2SO4 → MgSO4 + H2 (Balanced equation: Magnesium reacts with sulfuric acid to produce magnesium sulfate and hydrogen gas.)
3. CuO + Al → Al2O3 + Cu (Balanced equation: Copper(II) oxide reacts with aluminum to produce aluminum oxide and copper.)
4. Cu + ZnCl2 → ? (This reaction is not specified, and the products are missing.)
5. Zn + CuSO4 → ZnSO4 + Cu (Balanced equation: Zinc reacts with copper sulfate to produce zinc sulfate and copper.)

Please provide more information about the missing reactions, and I can help you balance them as well.
