Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca ( OH) 2. It is a colorless crystal or white powder and is produced when quicklime ( calcium oxide) is mixed with water. Annually, approximately 125 million tons of calcium hydroxide are produced worldwide.

An anhydrase is defined as an enzyme that catalyzes the removal of a water molecule from a compound, and so it is this "reverse" reaction that gives carbonic anhydrase its name, because it removes a water molecule from carbonic acid. In the lungs carbonic anhydrase converts bicarbonate to carbon dioxide, suited for exhalation.
In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p⦵ = 105 Pa (= 100 kPa = 1 ...
Calcium hypochlorite. Cl [O-]. [Ca+2].Cl [O-] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Calcium hypochlorite is an inorganic compound with chemical formula Ca ( Cl O)2, also written as Ca (OCl)2. It is a white solid, although commercial samples appear yellow.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

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 ...
Calcium hydride is a relatively mild desiccant and, compared to molecular sieves, probably inefficient. [ 7] Its use is safer than more reactive agents such as sodium metal or sodium-potassium alloy. Calcium hydride is widely used as a desiccant for basic solvents such as amines and pyridine. It is also used to dry alcohols.
Carbonic acid is a chemical compound with the chemical formula H 2 C O 3. The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature. [ 5][ 6] The interconversion of carbon dioxide and carbonic acid is related to the breathing cycle of animals and ...
