Question

What is the difference between displacement and double displacement

reactions? Write two chemical equations each for these reactions.​

Answer 1

Displacement reaction:

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

ex- Zn+2HCl⟶ZnCl2+H2

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.

ex- MgCl2+2KOH⟶Mg(OH)2+2KCl

Answer 2

Explanation:

Solution : In a displacement reaction, a more reactive element replaces a less reactive element from a compound <br> For Example : `CuSO_(4)(aq)+Zn(s) rarr ZnSO_(4)(aq) + Cu(s)` <br> In a double displacement reactions, two atoms or a group of atoms switch places to form new compounds <br>
