Question

wt is difference between displacement reaction and double displacement reaction ​

Answer 1

Answer:

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.

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products

ANSWER :

DISPLACEMENT REACTION :

A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. 

For example,

2HCl(aq)+Zn(s)→ZnCl2(aq)+H2(g) 

The hydrogen atoms in HCl are replaced by Zn atoms, and in the process a new element hydrogen is formed. 

DOUBLE DISPLACEMENT REACTION:

A double-displacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds. A characteristic of a double-replacement equation is that there are two compounds as reactants and two different compounds as products.

 An example :

CuCl2(aq)+2AgNO3(aq)→Cu(NO3)2(aq)+2AgCl(s)

There are two equivalent ways of considering a double-replacement equation,either the cations are swapped, or the anions are swapped.
