Give an example of a double displacement reaction other than the one given in image.
Sodium carbonate reacts with calcium chloride to form calcium carbonate and sodium chloride.
$\underset{\begin{smallmatrix} Sodium ~\\ carbonate~ \end{smallmatrix}}{\mathop{N{{a}_{2}}C{{O}_{3(aq)}}}}\,+\underset{\begin{smallmatrix} ~ \end{smallmatrix}}{\mathop{CaC{{l}_{2(aq)}}}}\,$ $\to \underset{Calcium~chloride~}{\mathop{CaC{{O}_{3(s)}}}}\,+\underset{Calcium\,\,\,carbonate}{\mathop{2NaC{{l}_{(aq)}}}}\,$
In this reaction, sodium carbonate and calcium chloride exchange ions to form two new compounds. Hence, it is a double displacement reaction.
