Question

Can any one give this answer

Answer 1

that both are the reaction of a metal with acid that oxidized metal and reduce acid , in which a salt is produced i.e.,ZnSO4&MnCl2

Answer 2

We know that more reactive element displaces less reactive element from its solution so:-

a) Zinc displaces hydrogen from sulphuric acid and forms zinc sulphate. It means Zinc is more reactive than hydrogen.

b) Magnesium displaces hydrogen from hydrochloric acid and forms Magnesium chloride. It means magnesium is more reactive than Hydrogen.

Hope it helps.
