Answer 1

${\underline{\underline{\huge{\mathscr{\orange{Answer:-}}}}}}$

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

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

In a double displacement reaction, two displacements take place to complete the reaction.

Answer:

In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds. ... In a double displacement reaction, two displacements take place to complete the reaction.

Explanation:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.

Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place. For example, when a solution of barium chloride is mixed with sodium sulphate, a white precipitate of barium sulphate is formed rapidly. These reactions are ionic in nature.
