ii) Differentiate between displacement and double displacement reaction. Give example.​

Answer 1

Explanation:

this is both that different between which you want

Answer 2

Answer:

1 .combination

A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).

Such reactions may be represented by equations of the following form: X + Y → XY.

decomposition-

A decomposition reaction can be defined as a type of chemical reaction in which under suitable conditions, one single compound splits into multiple simpler substances.

Example

HCl(aq) + NaOH(aq) → NaCl(aq) + HOH(l)

2. displacement reaction

2. displacement reaction

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

In a displacement reaction, one displacement takes place.

A + BX → AX + B

Double displacement reaction

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.

AB + CD → AC + BD
