Heating Limestone in a Lime Kiln: Exothermic Reaction

Explanation:
- When limestone (calcium carbonate) is heated in a lime kiln, it undergoes a chemical reaction to form quicklime (calcium oxide) and carbon dioxide gas.
- The chemical equation for this reaction is: CaCO3(s) → CaO(s) + CO2(g)

Exothermic Reaction:
- This reaction is exothermic, which means it releases heat energy to the surroundings.
- The energy released during the formation of quicklime is in the form of heat, making the surroundings feel warmer.
- This is because the bonds in the reactants (limestone) are broken and new bonds are formed in the products (quicklime), releasing energy in the process.

Key Points:
- Heating limestone in a lime kiln to form quicklime is an exothermic reaction.
- The reaction releases heat energy to the surroundings.
- Quicklime is formed by breaking bonds in limestone and forming new bonds in quicklime.
- The heat released during the reaction is a result of the energy released in bond formation.

In conclusion, the process of heating limestone in a lime kiln to form quicklime is an exothermic reaction. The release of heat energy during this reaction is due to the breaking and formation of chemical bonds, resulting in the formation of quicklime and carbon dioxide gas.
