With Answer of ur Question


The formula of Sulphuric acid is H2SO4

Now, zinc is more reactive than Hydrogen. So it displaces Hydrogen from H2SO4 which release H2 gas. The reaction is -

Zn + H2SO4 - Zn2SO4 + H2

But copper is less reactive than Hydrogen. So it can't displace Hydrogen from H2SO4.

Cu + H2SO4 - No reaction
