Question

Q15. Distinguish between a displacement and a double displacement reaction.

Answer 1

Answer:displacement

1 in 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
