Enthropy Change
The reaction of ammonium nitrate when added to water is endothermic (H=25.7 kJ) and can be written as:
NH4NO3(s) + H2(l) ---> NH4NO3(aq)
a) Determine the heat of formation of NH4HO3(aq)
b) What would be the final temperature of a solution that contained 50 grams of NH4NO3 dissolved in 125 mL of water. Use a specific heat of 4.18 J/(g °C) for the solution, an initial temp of 25 °C and no loss of heat to the surroundings.
