Question
**INTERACTIVE EXAMPLE: Using Enthalpies of Formation**

Nitroglycerin is a powerful explosive that forms four different gases when detonated:

\[ 2 \, \text{C}_3\text{H}_5(\text{NO}_3)_3 (l) \rightarrow 3 \, \text{N}_2 (g) + \frac{1}{2} \, \text{O}_2 (g) + 6 \, \text{CO}_2 (g) + 5 \, \text{H}_2\text{O} (g) \]

Calculate the enthalpy change that occurs when 18.0 g of nitroglycerin is detonated. The standard enthalpies of formation are shown below.

\[ \Delta H^\circ \, (\text{kJ/mol}) \]

- \(\text{C}_3\text{H}_5(\text{NO}_3)_3 (l): -364\)
- \(\text{CO}_2 (g): -393.5\)
- \(\text{H}_2\text{O} (g): -241.8\)
