The equation Na2CO3 + SiO2 -> 2Na2SiO3 + 2CO2

1. Detailed Information about the Equation Na₂CO₃ + SiO₂ -> 2Na₂SiO₃ + 2CO₂

The above equation represents the chemical reaction that occurs between sodium carbonate (Na₂CO₃) and silicon dioxide (SiO₂), resulting in the formation of sodium silicate (Na₂SiO₃) and carbon dioxide gas (CO₂).

2. Reaction Conditions

This reaction occurs at high temperatures, usually in a furnace at temperatures of around 800-900 degrees Celsius.

3. Reaction Process

In this reaction, sodium carbonate and silicon dioxide are heated in the furnace. When the temperature is high enough, Na₂CO₃ and SiO₂ combine to form sodium silicate and carbon dioxide gas. Carbon dioxide is released during the reaction process, while sodium silicate remains in the furnace.

4. Occurring Phenomenon

The observable phenomenon when the reaction occurs includes the release of carbon dioxide gas (CO₂) and the formation of sodium silicate (Na₂SiO₃), a white or beige solid substance.
