Question

How displacement reaction is different from double displacement reaction . Explain with an example?

Answer 1

1) AgNO³ + NaCl –––> AgCl + NaNO³. Ex. of double displacement.

2) Zn + 2HCl –––> ZnCl² + H². Ex. of displacement reaction.

In double displacement reactions, ions get exchanged. In displacement reaction ion displaces from less reactive metal to more reactive metal.

if you are satisfy with my ans then mark me as a brainlist.

if there is something wrong then kindly rectify it.

Answer 2

Explanation:

A double displacement reaction is a type of chemical reaction where two compounds react, and positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products. For example,

Na
