Limestone is calcium carbonate (CaCO3) which when heated to above 840°C decomposes into calcium oxide (CaO) while releasing carbon dioxide (CO2) according to the equation: CaCO3(s) → CaO(s) + CO2(g).
CaO is commonly known as lime, quicklime, or burnt lime. Click the Wikipedia article link below for information on its uses and history.

What is the difference between quick lime and lime water?
Quick lime is calcium oxide, CaO. Lime water is calcium hydroxide, Ca(OH)2 dissolved in water. Lime water can be made by dissolving quick lime in water.
When a chalk is heated it produces?
lime
Is quick lime an acid?
Quick lime is a base. It reacts vigourously with water (hence the term "quick" living, as "quick and the dead") CaO + H2O -> CaOH + OH-
How is slake lime made?
adding water to quick lime produces slaked lime.
What chemical is lime?
Lime is composed of the bodies of countless tiny animal shells, and is mainly CaCO3. When heated, the carbonate is driven off, leaving the highly reactive 'quick lime'. Which is quite alkaline and should not be handled directly.
Why is carbon dioxide produced in the lime kiln?
In a lime kiln calcium carbonate is heated to form quick lime and carbon dioxide. CaCO3 -> CaO + CO2
What is the difference between quick lime and lime water?
Quick lime is calcium oxide, CaO. Lime water is calcium hydroxide, Ca(OH)2 dissolved in water. Lime water can be made by dissolving quick lime in water.
What is the element present in quick lime?
There are TWO(2) elements present in quicklime. They are calcium and oxygen. Chemically it is calcium oxide (CaO).
When a chalk is heated it produces?
lime
How many element are present in quick lime?
Two elements--calcium and oxygen--are present in quick lime.
What is the symbol for lime?
CaO <-- this is also called as quick lime
Is quick lime an acid?
Quick lime is a base. It reacts vigourously with water (hence the term "quick" living, as "quick and the dead") CaO + H2O -> CaOH + OH-
How is slake lime made?
adding water to quick lime produces slaked lime.
What is the difference of quick lime and washing soda?
Quick lime is calcium oxide. Washing soda is sodium carbonate.
What chemical is lime?
Lime is composed of the bodies of countless tiny animal shells, and is mainly CaCO3. When heated, the carbonate is driven off, leaving the highly reactive 'quick lime'. Which is quite alkaline and should not be handled directly.
Which compound should be heated with soda lime to obtain ethane gas in the laboratory its equation?
Sodium propanoate (or propionate) when heated with soda lime ethane gas is produced.
How is quick lime made?
Limestone, calcium carbonate, is heated until it glows. It will give off carbon dioxide and change into calcium oxide. Calcium oxide is called quicklime because it hisses and swells up when a drop of water is added to it, just as if it was alive. "Quick" used to be used to indicate that something was living, so in this case it would be alive-lime, or quicklime.
