Explanation / Answer

Balanced chemical reaction for decomposition:

NH4NO3(s) = N2O(g) + 2 H2O(l)

(The phases are in bracket.)

standard enthalpy of formation of N2O=82.05 kJ

enthalpy of formation of H2O=-285.8 kJ

heat of reaction= (product-reactant)

= -365.1 - ((2*-285.8) + 82.05) kJ

= -124.45 kJ
