Ammonium nitrate is a common ingredient in fertilizers that can also be used to make explosives because it decomposes as follows:
NH4NO3(s) ? 2 N2(g) + O2(g) + 4 H2O(g) ?H = -236 kJ
The following questions deal with the decomposition of 12.1 g of NH4NO3:
(a) How much heat is liberated under standard conditions?
(b) How much work would be done by the gases at 310.°C?
(c) What volume of gas would be produced at 1.05 atm pressure and 310.°C?
