Question

what do you mean by displacement reaction​

Answer 1

Answer:

Displacement reaction: It is a reaction in which the compounds are displaced by the other element.... This reaction is known as the " displacement reaction"

There are some examples

They are as follows

Zn+Cuso4=ZnSO4+Cu

Zn+H2SO4=ZnSO4+H2

From these reactions,we conclude that the zinc is displacing the copper from the copper sulphate compound...

But , Fe+ZnSO4=NO REACTION

so the above reaction is not feasible...

Hence it doesn't occurs.....

Explanation:

Hope it helps you frnd.......

Answer 2

Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal. ... The atoms of the reactive magnesium give away electrons.
A + B-C → A-C + B. The above equation exists when A is more reactive than B
