Some ionic compounds are hydrates - solid compounds to which is bound a specific percentage of water. Some hydrates melt when heated and release energy when they solidify. For example, at
32°C, liquid Glauber's salt - sodium sulphatedecahydrate, Na2S04. 10H,0(1) - solidifies and releases 78.0 KJ/mol of energy. Calculate the enthalpy change when 2.50kg of Glauber's salt enters the solid
state?
