Question

how is displacement reaction different from double displacement reaction give its two example​

Answer 1

Answer:

A double displacement reaction is a type of reaction where two reactants exchange ions to form two new compounds. Double displacement reactions typically result in the formation of a product that is a precipitate.

The reaction between silver nitrate and sodium chloride is a double displacement reaction. The silver trades its nitrite ion for the sodium's chloride ion, causing the sodium to pick up the nitrate anion.

AgNO3 + NaCl → AgCl + NaNO3

Here's another example:

BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq)

A displacement reaction is a type of reaction where part of one reactant is replaced by another reactant. A displacement reaction is also known as a replacement reaction or a metathesis reaction. 

An example is the reaction between iron and copper sulfate to produce iron sulfate and copper:

Fe + CuSO4 → FeSO4 + Cu

Here, both iron and copper have the same valence. One metal cation takes the place of the other bonding to the sulfate 

Answer 2

Answer:

in displacement reaction, high reactive metal elements displaces low reactive metal element.

eg- A+BC--- AC+B

Fe+ CuSO4 (aq)---FeSO4+Cu

In double displacement, there is an exchange of Ions take place between the reactant

eg- AB + CD --- AD + CB

AgNO3 (aq) +NaCl (aq) --- AgCl (aq) +NaNO3 (aq)

I hope this answers help you
