Which of the following statements is not correct?
Copper is below hydrogen in the reactive series. Only a more reactive metal can displace a less reactive metal but Copper is less reactive than hydrogen and hence cannot liberate hydrogen from acids.
Cu + 2H2SO4→ CuSO4 + SO2 + 2H2O
3Cu + 8HNO3→ 3Cu(NO3)2 + 2NO + 4H2O
