![**Thermodynamics Reaction Calculations**
Enter your answer in the provided box.
**Calculate ΔH°<sub>rxn</sub> for the following reaction:**
\[ \text{SiO}_2(s) + 4 \text{HF}(g) \rightarrow \text{SiF}_4(g) + 2 \text{H}_2\text{O}(l) \]
**Given Standard Enthalpies of Formation (ΔH°<sub>f</sub>):**
- ΔH°<sub>f</sub> [SiO<sub>2</sub> (s)] = -910.9 kJ/mol
- ΔH°<sub>f</sub> [HF (g)] = -273 kJ/mol
- ΔH°<sub>f</sub> [SiF<sub>4</sub> (g)] = -1614.9 kJ/mol
- ΔH°<sub>f</sub> [H<sub>2</sub>O (l)] = -285.840 kJ/mol
