Question

what is the difference between displacement and double displacement reactions ? write equation for these reactions

Answer 1

Displacement Reaction:
A chemical Reaction, in which high reactive element displaces less reactive element.
For example:
When zinc reacts with hydrochloric acid we get zinc chloride and Hydrogen gas.
Here zinc is more reactive than hydrogen.
Zn(s) + HCl(aq)------> ZnCl2(aq) + H2(g)
Double Displacement teaction:
A chemical Reaction which involves mutual exchange of ions among its reactants to form new products.
Example:
Barium chloride reacts with sodium sulphate to form a precipitate of barium sulphate and sodium chloride.
BaCl2 (aq)+ Na2SO4 (aq)---> BaSO4(s) + 2NaCl(aq)

☺ Hello mate__ ❤

◾◾here is your answer...

✒DEFINITION OF DISPLACEMENT REACTION::--

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

i.e. A + BX. -----> AX + B

where A is more reactive than B

Example :-

CuSO4 + Zn --> ZnSO4 + Cu

✒DEFINITION OF DISPLACEMENT REACTION::--

In a double displacement reaction, two atoms or a group of atoms change places to form new compounds.

i.e. AB + CD ---> AC + BD

Example:--

Na2SO4 + BaCl ---> NaSO4 + 2NaCl
