Question

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

Answer 1

In displacement reaction one element displaces another element from its compound and takes its place therein. ... Double displacement : The reaction in which the constituent atoms of the reaction interchange by the decomposition of the two reactants, to produce new compounds are called double displacement reactions

Answer 2

Answer

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

For Example: CuSo4 (aq) + Zn (s) → ZnSO4 (aq) + Cu (s)

In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.

For Example: Na2SO4 (aq) + BaCl2 (aq) → BaSO4 (s) + 2NaCl (aq)
