Questions
Write chemical equation for the event.
Iron filings are dropped in aqueous solution of copper sulphate.
Iron dissolved in aqueous solution of copper sulphate.

Solution
Iron displaces copper from copper sulphate solution forming ferrous sulphate and copper.
\[\ce{\underset{\text{Iron}}{Fe_{(s)}} + \underset{\text{Copper sulphate}}{CuSO_{4(aq)}} -> \underset{\text{Ferrous sulphate}}{FeSO_{4(aq)}} + \underset{\text{Copper}}{Cu_{(s)}}}\]
