What is the product formed when calcium carbonate is heated strongly?
Calcium oxide and Carbon dioxide
Calcium hydroxide and Water
Calcium chloride and Oxygen
Calcium oxide and Carbon monoxide
Calcium oxide and Carbon dioxide
When calcium carbonate is strongly heated, it undergoes thermal decomposition to form calcium oxide (commonly known as quicklime) and carbon dioxide gas.
When calcium carbonate is strongly heated, it undergoes thermal decomposition to form calcium oxide (commonly known as quicklime) and carbon dioxide gas.
Heating limestone in a kiln to make quicklime for whitewashing or mortar is a classic industrial application of this thermal breakdown.
CaCOтВГ splits with heat: CaO gets left, COтВВ takes flight!
CaCO3тАЛ(s)╬ФтАЛCaO(s)+CO2тАЛ(g) тАФ Thermal decomposition reaction
The reaction is an endothermic process where heat energy breaks the chemical bonds in the calcium carbonate lattice. The absorption of heat drives the release of carbon dioxide gas, leaving behind solid calcium oxide.
Calcium carbonate is a key component of limestone, marble, and chalk.
This is a classic thermal decomposition reaction requiring high temperatures.
Carbon dioxide gas is evolved during the process, which can be tested using lime water.
Manufacture of cement and glass
Production of quicklime for construction and metallurgical processes
Option A is correct because limestone decomposes thermally into quicklime and carbon dioxide.
Option B (Calcium hydroxide) is formed by adding water to calcium oxide (slaking of lime).
A is correct тАФ Strong heating of calcium carbonate yields calcium oxide and carbon dioxide gas via thermal decomposition.
Always remember that most metal carbonates decompose upon strong heating to give their respective metal oxides and carbon dioxide gas.
