Write true or false for the following statement:
The reaction $Zn(s) + CuSO_4(aq) \longrightarrow ZnSO_4(aq) + Cu(s)$ is an example of a double displacement reaction.
The reaction $Zn(s) + CuSO_4(aq) \longrightarrow ZnSO_4(aq) + Cu(s)$ is an example of a double displacement reaction.
(FALSE) False.
This reaction is an example of a displacement reaction (specifically,a single displacement reaction).
In this reaction,a more reactive metal,$Zn$,displaces a less reactive metal,$Cu$,from its salt solution $(CuSO_4)$.
$A$ double displacement reaction involves the exchange of ions between two reactants,which is not the case here.
