This is ______ type of chemical reaction.

Options

• displacement 

• double displacement

• combination 

• decomposition

Answer 1

\[\ce{CuSO4_{(aq)} +  Zn_{(s)} -> ZnSO4_{(aq)} + Cu_{(s)}}\]

This is displacement type of chemical reaction.

Explanation:

A more reactive metal (Zn) displaces a less reactive metal (Cu) from its compound (CuSO₄) forming zinc sulphate (ZnSO₄) and solid copper Cu. This follows the reactivity series of metals.
