Occurrence, properties, and uses Calcium does not occur naturally in the free state, but compounds of the element are widely distributed. One calcium compound, lime (calcium oxide, CaO) was extensively used by the ancients.The silvery, rather soft, lightweight metal itself was first isolated (1808) by Sir Humphry Davy after distilling mercury from an amalgam formed by electrolyzing a mixture
A (quite vigorous) metal-acid reaction takes place, producing CaCl2 and hydrogen gas. Such a reaction is best carried out in the lab under a fume hood and using small pieces of calcium metal & dilute acid, as large pieces can produced sufficient h

Metal simplifies synthesis of antibody drugs by Rice University Rice University chemists have designed a plug-in metalloprotein to simplify the task of making targeted antibody therapies.
However, it was established that the successful sol–gel synthesis of appropriate calcium stannates (CaSnO 3 and Ca 2 SnO 4) can be performed only at acidic sol–gel processing conditions. Moreover, the influence of nature of alkaline earth metal source on the phase purity of different metal …

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, with all substances in their standard states.The standard pressure value p ⦵ = 10 5 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used.
