Question

Distinguish d/w displacement and double displacement reaction

Answer 1

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

Answer 2

Using balanced chemical equation, explain the difference between a displacement reaction and a double displacement reaction. Answer: Displacement Reaction: One element takes the place of another element in a compound. Double displacement Reaction: Two compounds react by an exchange of ions to form two new compounds.
