Displacement reaction is a reaction in which an elementary substance displaces and sets free a constituent element from a compound. but there is a single displacement reaction and double.


example 1

Single displacement: This is when one element trades places with another element in a compound. These reactions come in the general form of:

A + BC ---> AC + B


One example of a single displacement reaction is when magnesium replaces hydrogen in water to make magnesiumhydroxide and hydrogen gas:

Mg + 2 H2O ---> Mg(OH)2 + H2
