Question

different between displacement and double displacement reaction
​

Answer 1

Answer:

Displacement reaction is a chemical change, in which a more active element displaces a less reactivate element from its salt solution. ... Double displacement reaction is a chemical change in which two compounds exchange their radicals with each other to form new compounds. Example - Mg + H2So4 ---> MgSo4 + H2.

Answer 2

➣ AnSwer :-

⟹ Displacement reaction :-

• A displacement reaction is the one wherein the atom or a set of atoms is displaced by another atom in a molecule.
• For instance, when Iron is added to a copper sulphate solution, it displaces the copper metal.

A + B-C → A-C + B

• The above equation exists when A is more reactive than B.

⟹ Double displacement reaction :-

• A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds.
• The general form of a double-replacement (also called double-displacement) reaction is:

AB+CD→AD+BC
