2. The process of dissolving ammonium nitrate, NH4NO3, in water is an endothermic process.
a) What is the sign of q?
b) If you were to add some ammonium nitrate to water in a flask, would you expect the
flask to feel warm or cool?
c) Commercial cold packs consist of solid ammonium nitrate and water. NH. NO:
absorbs 3,30 x 10- J of heat per gram dissolved in water. In a coffee-cup calorimeter.
4,40 g NHANO, is dissolved in 100,0 g of water at 21,0 °C. What is the final
temperature of the solution? Assume that the solution has a specific heat capacity of
4.18 J/gK lo
