Answer 2

Answer:

Displacement reaction is a chemical reaction in which one element is replaced by another in a compound.

AB + C → AC + B

Double Displacement is when two atoms switch their places in a chemical reaction.

AB + CD → AD + BC

Examples:

2NaCl + CaSO$_{4}$ → Na$_{2}$SO$_{4}$+ CaCl

In this double displacement reaction, Cl and SO$_{4}$ for this reaction.

CuSO$_{4}$ + Zn → ZnSO$_{4}$ + Cu

In this displacement reaction,  Zn displaces Cu (This happens becoz of the reactivity series)

Ps. Sorry this answer took so long, I had to gather materials as I typed since I am not a topper either. Hope this helps.
