First of all, I agree this paper was way different and more harder compared to all the past papers I've seen!
And I thought it was asking for hydrated crystals so it was going backwards so
I wrote -DeltaH1 + Delta H2.. I have no clue though :p

it was asking for formation of hydrated crystals, so it is an exothermic reaction. the other 2 are endothermic as u form dehydrated sodium something (cant rmember the compound name exactly). delta h1 = delta hf + delta h2. re arrange, it becomes delta hf = delta h1 - delta h2
