The correct Answer is:
To determine which substances react with Silicon Dioxide (SiO₂), we can analyze each option provided in the question. ### Step-by-Step Solution: 1. **Identify the Reactants**: The reactants we need to consider are Sodium Carbonate (Na₂CO₃), Carbon Dioxide (CO₂), Hydrogen Fluoride (HF), and Hydrogen Chloride (HCl). 2. **Reaction with Sodium Carbonate**: - **Equation**: SiO₂ + Na₂CO₃ → Na₂SiO₃ + CO₂ - **Analysis**: Silicon Dioxide reacts with Sodium Carbonate to produce Sodium Metasilicate (Na₂SiO₃) and Carbon Dioxide (CO₂). - **Conclusion**: SiO₂ reacts with Sodium Carbonate. 3. **Reaction with Carbon Dioxide**: - **Equation**: SiO₂ + CO₂ → No Reaction - **Analysis**: Silicon Dioxide does not react with Carbon Dioxide. - **Conclusion**: SiO₂ does not react with Carbon Dioxide. 4. **Reaction with Hydrogen Fluoride**: - **Equation**: SiO₂ + 4HF → SiF₄ + 2H₂O - **Analysis**: Silicon Dioxide reacts with Hydrogen Fluoride to produce Silicon Tetrafluoride (SiF₄) and water (H₂O). - **Conclusion**: SiO₂ reacts with Hydrogen Fluoride. 5. **Reaction with Hydrogen Chloride**: - **Equation**: SiO₂ + HCl → No Reaction - **Analysis**: Silicon Dioxide does not react with Hydrogen Chloride. - **Conclusion**: SiO₂ does not react with Hydrogen Chloride. ### Final Conclusion: Based on the analysis: - SiO₂ reacts with Sodium Carbonate (Na₂CO₃). - SiO₂ reacts with Hydrogen Fluoride (HF). - SiO₂ does not react with Carbon Dioxide (CO₂) or Hydrogen Chloride (HCl). ### Answer: Silicon Dioxide (SiO₂) reacts with: - A) Sodium Carbonate (Na₂CO₃) - C) Hydrogen Fluoride (HF)
