SUMMARY
The reaction between gaseous hydrofluoric acid (HF) and solid silicon dioxide (SiO2) does not yield the expected products as initially proposed. The correct understanding of the valence electrons is crucial, with silicon (Si) exhibiting a +4 oxidation state in this context. The confusion arises from the nature of the reaction, which is not a simple double replacement due to the solid-state of SiO2 and the gaseous nature of HF. Proper memorization of chemical rules and periodic table trends is essential for accurate predictions in such reactions.
