$\implies$Displacement reaction is a chemical reaction in which one reactant present in the equation is displaced with the other reactant and owing to this phenomenon this reaction is also called the replacement reaction.

Answer 2

Answer:

A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound

Step-by-step explanation:

In beaker A Zn being more reactive than copper replaces copper from the solution of copper sulphate and forms zinc sulphate.

CuSO4 + Zn --> ZnSO4 + Cu

In beaker B iron being more reactive than copper replaces it from its solution and forms iron sulphate.

 CuSO4 + Fe --> FeSO4 + Cu

In beaker C there would be no reaction as less reactive metal (copper) cannot displace more reactive metal (zinc) from its solution.

In beaker D there would be no reaction as less reactive metal (copper) cannot displace more reactive metal (iron) from its solution.

In beaker E there would be no reaction as less reactive metal (iron) cannot displace more reactive metal (zinc) from its solution.
