ANSWER :
DISPLACEMENT REACTION :
A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products.
For example,
2HCl(aq)+Zn(s)→ZnCl2(aq)+H2(g)
The hydrogen atoms in HCl are replaced by Zn atoms, and in the process a new element hydrogen is formed.
DOUBLE DISPLACEMENT REACTION:
A double-displacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.
An example :
CuCl2(aq)+2AgNO3(aq)→Cu(NO3)2(aq)+2AgCl(s)
There are two equivalent ways of considering a double-replacement equation,either the cations are swapped, or the anions are swapped.
