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.
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.
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.
Sodium propanoate (or propionate) when heated with soda lime ethane gas is produced.
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.
In a lime kiln calcium carbonate is heated to form quick lime and carbon dioxide. CaCO3 -> CaO + CO2
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.

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.

When soda lime and egg albumin are heated together, the gas formed is ammonia. Ammonia is produced due to the decomposition of egg albumin by soda lime, releasing ammonia gas as a byproduct.
