Cu + H2SO4 = CuSO4 + H2
Cu + 2H2SO4 ---> CuSO4 + 2H2O + SO2 This reaction only happens when the sulfuric acid is hot and concentrated.
CuO + H2SO4 --> CuSO4 + H2O
Cu + 2 H2SO4 ----> 2H2O+ CuSO4 + SO2Rebalanced by Graphyx
neutralisation
Copper oxide+ Sulphuric acid ----> copper sulphate +water
4. The chemical equation is Cu + H2SO4 → CuSO4 + H2. Copper and sulfuric acid have the same coefficient (1), so the same number of moles of copper and sulfuric acid are used.

The word equation for the reaction between magnesium carbonate and sulfuric acid is Magnesium Carbonate + Hyrdocholric Acid > Magnesum Chloride + Carbon Dioxide + Water.
It depends on the solid!
magnesium carbonate + sulfuric acid = magnesium oxide= carbon dioxide
CuO + H2SO4 --> CuSO4 + H2O
This equation is CaO + H2SO4 = CaSO4 + H2O.
