Question 1

The heat of solution of NH4NO3 is 26.2 kJ/mol.  Is heat evolved or absorbed when a solution of NH4NO3 is diluted by addition of more water?


Question 2

The heat released when one mole of water is formed from the elements is 1,198 kJ.  An experiment was conducted that permitted water to form in this manner, and the heat was contained in 2.0 liters of water. The water temperature before the reaction was 34.5°C, and after the reaction it had risen to 52.0°C.  How many moles of water were formed?  (The specific heat of water is 4.184 J/g·°C.)
