question 122

Essay

When ammonium nitrate (NH₄NO₃)(s) is used in explosives, it decomposes to N₂(g), O₂(g), and H₂O(g). Write a balanced reaction equation for the decomposition of ammonium nitrate, and determine the standard enthalpy of reaction using standard enthalpies of formation:
solid ammonium nitrate = -366 kJ/mol and water vapor = -242 kJ/mol.
