Decomposition of limestone to quick lime and carbon dioxide is an example of which of the following types of reaction?
Thermal decomposition
The decomposition of limestone (CaCO3) to quicklime (CaO) and carbon dioxide (CO2) is an example of a thermal decomposition reaction. This is a type of chemical reaction where a compound breaks down into two or more components when heated. In this case, heat causes limestone to decompose into quicklime and carbon dioxide gas.
The chemical equation for this reaction is as follows:
CaCO3 (s) → CaO (s) + CO2 (g)
