Nitroglycerine, C3H5(NO3)3(l), a powerful explosive used in

mining, detonates to produce a hot gaseous mixture of nitrogen,

water, carbon dioxide, and oxygen.

(a) Write a balanced equation for this reaction using the smallest

whole-number coefficients.

(b) If H°rxn 2.29104 kJ for the equation as written in

part (a), calculate H°f of nitroglycerine.
