Question

What is the difference between displacement and double displacement reactions? Write equations for these reactions.


NCERT Class 10th Science Chapter 1 Chemical Reactions and Equations

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

In displacement reaction a more reactive metal displaces less reactive metal from its compound ...
2) It is a very slow reaction.




Double displacement reaction- Those reactions in which two different atoms or groups of atoms are displaced by other atoms or groups of atoms..

2) These reaction takes place within fraction of time.
