In 1947, Texas City, Texas, was devastated by the explosion of a shipload of ammonium nitrate, a compound intended to be used as a fertilizer. When heated, ammonium nitrate can decompose exothermically to N,O and water. NH4NO3(s) → NO (g) + 2 H20(g) ∆H= -37.0 kJ If the heat from this exothermic reaction is contained, higher temperatures are generated, at which point ammonium nitrate can decompose explosively to N2, H2O, and O2. 2 NH4NO3(s) → 2 N2(g) + 4H2O(g) + 02(g) If oxidizable materials are present, fires can break out, as was the case at Texas City. If 12.7 kg ammonium nitrate explodes, calculate how much thermal energy is evolved (under standard conditions). N = 14 g/mol H = 1 g/mol O = 16 g/mol
