Answer
(i) iron + copper sulphate
iron sulphate + copper (ii) The nail would appear to be coated with copper, giving it a reddish-brown color.
Explanation
## Step 1: Understand the reactionThe reaction taking place is a displacement reaction. In this reaction, iron displaces copper from copper sulphate, resulting in the formation of iron sulphate and copper. ## Step 2: Complete the word equationThe word equation for the reaction can be completed based on the understanding of the displacement reaction. ### The word equation for the reaction is: **Iron + Copper Sulphate → Iron Sulphate + Copper**## Step 3: Describe the change on the nail surfaceWhen iron displaces copper from copper sulphate, the copper is deposited on the surface of the nail. This results in a change in the appearance of the nail.### The change on the nail surface is: **The nail would appear to be coated with copper, giving it a reddish-brown color.**
