CaCO₃ (s) → CaO (s) + CO₂ (g)
Here's a breakdown:
* CaCO₃ (s) represents solid calcium carbonate (limestone).
* CaO (s) represents solid calcium oxide (quicklime).
* CO₂ (g) represents gaseous carbon dioxide.
This reaction is a decomposition reaction, where one substance breaks down into two or more simpler substances. The heat provides the energy needed to break the bonds in calcium carbonate, releasing carbon dioxide gas and leaving behind calcium oxide.
