7. Ammonium nitrate and sodium hydroxide react to yield ammonia, water vapor, and sodium nitrate. Calculate the enthalpy of formation of sodium hydroxide given the following heats of
formation: ammonium nitrate AH°= -230.6 kJ/mol, ammonia AH = -46.2 kJ/mol, water vapor
AH° = -241.8 kJ/mol, sodium nitrate AH°= -467 kJ/mol, and AHºxxn = -55.2 kJ/mol.
