Question

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

Answer 1

Explanation:

Displacement Reactions- The chemical reaction in which more reactive elements displaces less reactive elements from its salt solution.

ex- Fe(s) + CuSO4(aq) = FeSO4 (aq) + Cu (s)

Double Displacement Reactions- A reactions in which new compounds are formed by mutual exchange of ions between two compounds.

ex- Na2SO4(aq) + BaCl2(aq) = BaSO4(s) + 2NaCl(aq)

Answer 2

Answer:

In a displacement reaction, a more reactive element replaces a less reactive element from a compound.

whereas In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds. ... Metals react with the salt solution of another metal.

Equations

Displacement reaction

Mg + CuSO4 ➡ MgSO4 + Cu

Double Displacement reaction

AgNO3 + KCl ➡ AgCl⬇ + KNO3
