Gypsum is hydrated calcium sulfat,CaSO4·xH2O.A residue of 5.65g of anhydrous calcium sulfate is obtained by heating 7.15g gypsum.Determine the empirical formula of gypsum不用翻译……尤其是拿翻译软件翻译的……这个太。咳咳要得是怎么写这个题~ ...
Three forms of calcium are in equilibrium in serum: nondiffusible calcium bound primarily to albumin; diffusible complexes of calcium with lactate, bicarbonate, phosphate, sulfate, citrate, and other anions; and diffusible ionized calcium (Ca2+). Ionized calcium accounts for approximately half the tot...

Write the formulae for the following compounds. (a) calcium acetate (b) iron(II) cyanide (c) sodium dichromate (d) Chromium(III) sulfate (e) mercury (II) perchlorate Write the empirical formula for at least four ionic compounds that could be formed from the following ...
What is the formula for iron 2 sulfate? What type of compound is calcium carbonate? How does beryllium react with water? Is iron a metal, nonmetal or metalloid? What is the chemical formula for magnetite? What is the electron configuration for calcium? What is the charge on the iron ion ...
The above results surprisingly show that a combination of 0.5% sodium lauryl sulfate with 0.5% croscarmellose sodium significantly minimizes the tablet disintegration aging phenomenon observed in the same formula without the surfactant added. In addition to the calcium phosphate, the microcrystalline cellulo...
All compositions disclosed therein contain sulfate. Polyaluminum calcium hydroxychloride solutions (PAC-Ca) containing amino acids are also known as antiperspirants of enhanced efficacy as described in U.S. Pat. Nos. 6,042,816 and 7,087,220. Also known is use of polyaluminum hydroxychlorides ...
These compounds are as follows: brownmillerite Ca4Al2Fe2O10, tricalcium aluminate Ca3Al2O6, and calcium sulfate and carbonate; together with calcium hydroxide and oxide, this makes approximately 50% of the gross composition of the fraction. The other crystalline phases of the dispersed fraction ...
