Molecular mass of calcium oxide

Calcium oxide formula : Ca O , commonly known as quicklime or burnt lime , is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium , aluminium , and iron predominate. By contrast, quicklime specifically applies to the single compound calcium oxide. Calcium oxide that survives processing without reacting in building products , such as cement , is called free lime. Quicklime is relatively inexpensive. Both it and the chemical derivative calcium hydroxide of which quicklime is the base anhydride are important commodity chemicals. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells , that contain calcium carbonate CaCO 3 ; mineral calcite in a lime kiln. This is also one of the few chemical reactions known in prehistoric times. The quicklime is not stable and, when cooled, will spontaneously react with CO 2 from the air until, after enough time, it will be completely converted back to calcium carbonate unless slaked with water to set as lime plaster or lime mortar. Annual worldwide production of quicklime is around million tonnes. China is by far the world's largest producer, with a total of around million tonnes per year. The United States is the next largest, with around 20 million tonnes per year. Approximately 1.

Calcium oxide, commonly known as lime, is a chemical compound with the formula CaO.

The United States is the next largest, with around 20 million tonnes per year. Both it and the chemical derivative calcium hydroxide of which quicklime is the base anhydride are important commodity chemicals. Limestone, which contains less reactive material, is slower to react and may have other disadvantages compared with lime, depending on the application; however, limestone is considerably less expensive than lime. These names refer to the traditional method of producing calcium oxide by heating calcium carbonate such as limestone to a high temperature, resulting in the decomposition of the carbonate and the formation of calcium oxide. Annual worldwide production of quicklime is around million tonnes. Unit converters. Chemical compound of calcium. Acidity p K a.
