Question

Q9) What is the difference between displacement and double displacement reaction? Write
equations for these reactions.​

Answer 1

Answer:

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. ... In a displacement reaction, one displacement takes place. A + BX → AX + B. In a double displacement reaction, two displacements take place to complete the reaction.

Answer 2

displacement reaction

A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule

.

. A + B-C → A-C + B.

for example: 1. Fe + CuSO4 FeSO4 + Cu.

2. 2K + MgCl2 2KCl + Mg.

double displacement reaction

Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place.

AB + CD → AD + CB

for example: 1. Na2CO3 + 2 HCl → 2 NaCl + H2CO3

2. Na2S+2HCl→2NaCl+H2S
