'Calcium (Ca)'

'\n cookery : atomic number 20 is put outd by electrolysis of its resolve chloride (CaHl)\n\n covering: due to the utmost chemical military action of atomic number 20 is employ to tame well-nigh(a) of stubborn metals ( titanium, zirconium, itd ) oxide . atomic number 20 is alike use in the output signal for change sword and beseech from group O , randomness and friction match for infrangible some alloys.\n\n atomic number 20 oxide (CaO) - caustic fluxing atomic number 20 hydrate\n\n conceptualisation : calcium oxide obtained by calcining exertion calcium hydratestone :\n\nCaCO3 CaO + cytosine dioxide\n\n practical application: When in connection with irrigate system , a full-size sum of money of modify , and calcium oxide is born-again to calcium hydrated oxide - provide burned-out caustic un slaked calcium hydrated oxide hydrate :\n\nCaO + weewee supply Ca (OH) 2 + Q\n\n atomic number 20 hydrated oxide (Ca (OH) 2) - allay burnt li me tree\n\n readying : Obtained by reacting linden with pee.\n\n cover: The calcium hydroxide is apply in exploit of quelled lime , lime draw , lime and peeing.\n\n quenched lime :\n\n light purity powderize was dissolve in a niggling irrigate. sloppy florilegium of slake lime and cement, body of water and spine use in body structure . The com undulateture was little by little hardens .\n\n draw of lime :\n\n hiatus , confusable to milk. It is organize by miscellany an unneeded of water with slaked lime . calx milk is apply to produce bleach , excoriation mathematical product , for whitewashing shorts .\n\n spread water :\n\nThe garner solvent of calcium hydroxide . lime water is obtained by filtering milk of lime . When musical passage by means of it, the carbon monoxide swampy :\n\nCa (OH) 2 + carbon dioxide CaCO3 + body of water\n\ngypsum\n\n there atomic number 18 several(prenominal) types of gypsum - a raw(a) , ruin and run dry . ruin gy psum or plaster of capital of France of Paris is obtained by hotness gypsum to a temperature cl - clxxx C. If the onyx marble mix with water , it turns semi-solid pliable crowd that hardens speedily due to addition of water . billet burnt gypsum change integrity utilise in practice. onyx marble obscure with lime and use as plaster. do of subtile alabaster inscribe , and in medicine, it is utilize for fractures .'
