it is because hydrogen gas usually liberates when an acid reacts with metal

Why does copper not evolve hydrogen on reacting with dilute sulphuric acid?
Standard reduction potential ( SRP) of copper is more ( + 0.34 v ) than that of Hydrogen ( 0.00 v )
What is the word equation of copper oxide reacting with sulfuric acid to make copper sulphate?
Copper oxide+ Sulphuric acid ----> copper sulphate +water
Why Isn't hydrogen gas formed from a mixture of copper carbonate and sulphuric acid?
hydrogen
What is the balanced symbol equation for copper ll oxide reacting with hydrogen?
The balanced symbol equation for copper II oxide reacting with hydrogen is Cu + H2O. This reaction will create copper and water as a result.
What is the reaction between copper and sulfuric acid?
No, there is no reaction between copper & H2SO4 because according to reactivity series of metal hydrogen is more reactive than copper. Hence copper does not displace hydrogen from sulphuric acid..

Why don't we make hydrogen when reacting an acid with copper?
Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.

Is hydrogen gas formed from a mixture of copper carbonate and sulphuric acid?
NO!
What equation is sulphuric acid mixed with copper oxide?
Cu + 2H2SO4 -> CuSO4 + 2H2O + SO2 Copper (Cu) on reacting with two moles of sulphuric acid (H2SO4) yields copper sulphate (CuSO4) and 2 moles of water (2H2O) and sulphur dioxide (SO2).
Is hydrogen formed from a mixture of copper carbonate and sulphuric acid?
no hidro means water
How does copper reacts with acid when copper is below hydrogen in reactivity series?
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.
Why does copper give off no hydrogen when reacting in water?
because it isn't a reactive metal
Why does sulphuric acid have to be warm to be used in the copper oxide reaction?
Because copper isn't reactive enough to displace hydrogen if the solution is cool or cold. It becomes easier for copper to replace the hydrogen when the solution is warm.
