Question

Explain zn react with dilute h2so4give h2 gas but cu does not

Answer 1

because in electro chemical series those element which before the H2 is more reactive and give H2 gas. Zn is before the hydrogen so it is react with dil H2SO4 and give H2 but in electro chemical series copper is placed after the hydrogen so it is less reactive and does not give H2 gas.
