Question

Pat, light and electricity
What is the difference between displacement reaction and double displacement reason? W
e chemical equations for these reactions.
wer the following questions:​

Answer 1

Displacement reaction:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.

Zn+2HCl⟶ZnCl2 +H 2

Double displacement reaction:

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 is called double displacement reactions.

Mgcl 2 +2KOH⟶Mg(OH) 2 +2KCl +2KCl
