1. Ammonium sulfate, (NH4)2SO4, is used as a fire retardant and wood preservative; it is prepared industrially by the highly exothermic reaction of gaseous ammonia with sulfuric acid: 2NH3(g) + H2SO4(aq) → (NH4)2SO4(5) The value of AHxºis -275.0 kJ/mol. Use the data on pg. 320 to calculate the standard enthalpy of formation of ammonium sulfate (in kilojoules per mole) [2 marks]
