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 ΔH°rxn= −2.29×104 kJ for the equation as written in part (a), calculate ΔH°f of nitroglycerine.
