Question

what is the difference between displacement and doulbe displacement reactions? write equations for these reactions​



--------

Answer 1

AnswEr:

Displacement Reaction:

1). In the Displacement Reaction, a less reactive Element displaced by more reactive Element.

2) In Displacement Reaction there is no precipitate formed as Double displacement reaction.

3). In Displacement Reaction Only One displacement takes place.

4).Example of Displacement Reaction is -

$\:\:\sf\: CuSO_{4} + Zn \longrightarrow ZnSO_{4}$

Double Displacement Reaction:

1). In the Double Displacement Reaction, there is an exchange of two ionic compounds & makes two new compounds.

2). In Double Displacement Reaction precipitate formed.

3) In Double Displacement Reaction, two displacement takes place.

4).Example of Double Displacement Reaction is -

$\;\;\sf\underbrace{CuCl_{2}}_{aq} + \underbrace{2AgNO_{3}}_{aq} \longrightarrow \underbrace{Cu(NO_{3})_{2}}_{aq}+ \underbrace{2AgCl}_{solid}$

Answer 2

Answer:

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. ... In a displacement reaction, one displacement takes place. A + BX → AX + B. In a double displacement reaction, two displacements take place to complete the reaction
