Sodium hydrogen carbonate → Sodium carbonate + Carbon dioxide + Water
Here's a more detailed breakdown:
* Sodium hydrogen carbonate (NaHCO₃) is the reactant, the substance being heated.
* Sodium carbonate (Na₂CO₃) is one of the products, a white solid.
* Carbon dioxide (CO₂) is another product, a colorless gas.
* Water (H₂O) is the final product, which can be seen as steam.
This reaction is also known as the thermal decomposition of sodium hydrogen carbonate.
