Reaction of different substances and their products

When iron reacts with copper sulphate, Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal so reaction occur.

Copper is a very unreactive metal, but it does not react with hydrochloric acid. The copper cannot replace the hydrogen in HCl to form CuCl2 so no reaction occurs.

When zinc reacts with copper nitrate, the zinc metal displaces the copper from copper nitrate produces zinc nitrate and copper metal so reaction occur.

When zinc metal reacts with an aqueous magnesium sulfate solution, the zinc displaces the magnesium ion forming zinc sulfate which is the indication of chemical reaction.

When zinc reacts with hydrochloric acid it produces zinc chloride and liberating hydrogen gas so we can say that reaction occur when the zinc combines with HCl.

When iron reacts with hydrochloric acid, it produces iron (II) chloride which is also called iron dichloride and hydrogen gas is released in the form of bubbles in the solution so reaction occurs.
