Answer 2

$\displaystyle\underline{\underline{\huge\sf Answer}}$

$\displaystyle\sf CuSO_4+Zn \dashrightarrow ZnSO_4+Cu$

$\displaystyle\underline{\bigstar\:\textsf{Explanation}}$

»» When this reaction happens, the solution's colour gets changed

• Blue ➝ Colourless

»» This is a displacement reaction where a High reactive metal replace a low reactive metal

»» Here we know that Zinc is more reactive than copper so zinc replaces copper to form Copper sulphate ($\displaystyle\sf ZnSO_4$)

»» The displacement reaction can be written as AB+C ➝ CB+A

• A is high reactive
• B is the non metal
• C is the high reactive metal
