Answer 2

Answer:

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule. For instance, when Iron is added to a copper sulphate solution, it displaces the copper metal.

A + B-C → A-C + B

The above equation exists when A is more reactive than B.

A and B have to be either:

Halogens where C indicates a cation.

Different metals wherein C indicates an anion.
