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.

Yes, calcium oxyde - CaO.
Quick lime or burnt lime is chemically known as Calcium oxide (CaO)It can be prepared by 'burning' or heating marble or limestone to above 825 °C, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln.CaCO3 --> CaO + CO2(gas)
Quick lime is obtained by heating (calcining) calcium carbonate. If the CaO obtained is reacted with water it produces slaked lime Ca(OH)2
Lime is a compound.
Quicklime is calcium oxide (CaO), a white crystalline solid obtained by heating limestone in a kiln. Lime water, on the other hand, refers to a saturated solution of calcium hydroxide (Ca(OH)2) in water. Quicklime is a solid, while lime water is a liquid solution.
Two elements--calcium and oxygen--are present in quick lime.
CaO <-- this is also called as quick lime
Quick lime is calcium oxide. Washing soda is sodium carbonate.
its kind of hard to explain. orignaly it dosent react with water (execpt from erosion) until it is made into calcium oxide using a blast furnace the new quick lime then is recated with water to form slaked lime which can be made into lime water by adding even more water. then there is another proces where slaked lime can be turned into limestone again and the whole cycle again. 1) calcium carobante + heat = quick lime + carbon doixide or CaCO3 + heat = CaO + C(O)2 2) quick lime + water = slaked lime CaO + (H)2O = Ca(OH)2
Quick lime is a base. It reacts vigourously with water (hence the term "quick" living, as "quick and the dead") CaO + H2O -> CaOH + OH-
Calcium and oxygen (calcium oxide) are present in quick lime.
adding water to quick lime produces slaked lime.
Calcium and oxygen (calcium oxide) are present in quick lime.
