Question

difference bettwen displacement and double displacement​

Answer 1

Explanation:

a) Those reactions in which one element takes the place of another element in a compound, are known as displacement reactions.

Equation: CuSO4 (aq) + Zn (s)  ZnSO4 + Cu

Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions.

Equation: AgNO3 (aq) + NaCl (aq)  AgCl (s)+ NaNO3 (aq)

(b) Any reaction in which an insoluble solid (called precipitate) is formed that separates from the solution is called a precipitation reaction.

Example: The reaction between barium chloride and sodium sulphate solution to form a white barium sulphate precipitate (alongwith sodium chloride solution) is an example of a precipitation reaction.

Answer 2

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. ... Metals react with the salt solution of another metal. Salt solutions of two different metals react with each other
