Jamir Callahan · Answer 1

A simple displacement reaction occurs when an iron nail is immersed to a beaker containing copper sulphate solution.

a)

Iron is more reactive than copper. As a result a displacement reaction will take place. The ferrous or Fe (II) irons will move to the solution. The copper ions (Cu II) will get deposited on the nail. This will cause the colour to change from blue to green.

b)

The equation can be written as:

Fe (s) + CuSO4 (aq) - > FeSO4 (aq) + Cu (s)

c)

A chemical change can be described as a change that causes a substance to change to another form. Hence, this reaction is a chemical change.
