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 -

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

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

existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.
