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.

Molecular mass of calcium oxide

Calcium oxide, commonly known as lime, is a chemical compound with the formula CaO. Calcium oxide, also known as quicklime , is an alkaline substance that has been in use since the medieval age. It is believed that quicklime is one of the oldest chemicals known to the human race. It can also be referred to as burnt lime or lime. Calcium oxide has a medium viscosity and a high surface tension, plus a high to intermediate expansion and contraction rate. Calcium oxide has a moderate effect on colour, except in large amounts when it may have a bleaching effect on iron oxide. This reaction is reversible and exothermic in nature in the forward direction.

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. Chemical forum. In this lattice structure, each calcium cation is surrounded by six oxygen anions, and each oxygen anion is surrounded by six calcium cations.
