Step 1: Identify the reaction type
This is a displacement reaction, where iron (Fe) displaces copper (Cu) from copper sulfate (CuSO4). In a displacement reaction, a more reactive element replaces a less reactive element from a compound.
Step 2: Conclusion
In this case, iron displaces copper from copper sulfate, forming iron sulfate and copper metal. This confirms it as a displacement reaction.
Final Answer: The correct reaction type is Displacement Reaction.

Which of the following is an example of an addition reaction?
Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
