 64 Name one metal more reactive and another less reactive than hydrogen. 64 Name one metal which displaces copper from copper sulphate solution and one which does not.

Solution||| the one metal which displaces copper from copper sulphate solution is zinc. Zinc displaces copper fro the solution of copper sulphate Solution|||The one metal which do not do so is mercury. As mercury do not displace copper from copper sulphate
