Question

what is the difference between displacement and double displacement reaction? write equation for the reaction ​

Answer 1

Displacement : 1. In displacement reaction more reactive metal displace less reactive metak from its compound

2. It is slow reaction

3.change of colour takes place

Ex=magnesium + aluminium oxide = magnesium oxide + aluminum

Double Displacement : 1. there is an exchange of ions between two reactant.

2.it is a fast reaction

3.precipited are formed

Ex the reaction between silver nitrate and sodium chloride is a double displacement reaction
