2:

Displacement
1in these reaction ,more reactive metal displace less reactive metal from its compound
2 it is a slow reaction
3 change of colour take place
4 e.g fe++cuso4 ---->feso4++cu

double displacement
1 there is an exchange of ions between two reactant
2 it is a fast reaction
3 precipitate are formed
4 e.g agno3++nacl-->agcl++nano3
