Hey mate,, here is ur ans..
- Almost every decomposition reaction is endothermic since energy is required to break bonds or decomposition of a compound.
- the colour of copper sulphate solution change when iron nail is dipped in it because in the reaction iron has replaced copper frm its solution.thus the amount of copper decreases n the colour fades.its colour changes to green frm blue..
CuSO₄ + Fe ⇒ FeSO₄ + Cu
#hope it helps

Hello user
Because energy is needed to break the bonds of the compound in order to decompose it so All decomposition reactions are endothermic reactions.
Ans 2... CuSO4 + Fe ----------- FeSO4 + Cu
Fe being more reactivr than Cu displaces Cu from CuSO4 and then form FeSO4 which gives the green color to solution
