Answer the following question: 
 
What is the difference between displacement and double displacement reactions? Write equations for these reactions.
 
In displacement reactions, a more reactive metal displaces a less reactive metal from its solution.
 
For example,
 
This is a displacement reaction where iron displaces copper from its solution.

In double displacement reactions, two reactants in solution exchange their ions.
 
For example,
 
This is a double displacement reaction where silver nitrate and sodium chloride exchange \(Cl^–\) and \(NO_3^–\) ions between them.
