CaSO 4 · 1 / 2 H 2 O + 1 + 1 / 2 H 2 O → CaSO 4 · 2 H 2 O. This reaction is exothermic and is responsible for the ease with which gypsum can be cast into various shapes including sheets (for drywall), sticks (for blackboard chalk), and molds (to immobilize broken bones, or for metal casting). Mixed with polymers, it has been ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
When calcium ions (Ca 2+) are depleted from the endoplasmic reticulum (a major store of Ca 2+) of mammalian cells, the CRAC channel is activated to slowly replenish the level of calcium in the endoplasmic reticulum. The Ca 2+ Release-activated Ca 2+ (CRAC) Channel (CRAC-C) Family (TC# 1.A.52) is a member of the Cation Diffusion Facilitator (CDF ...
Cr(η 6-C 6 H 6) 2, named as bis(η 6-benzene)chromium as all of the (contiguous) atoms in the benzene ligands are involved their position does not have to be specified [(1,2,5,6-η)-cycloocta-1,3,5,7-tetraene](η 5 -cyclopentadienyl)cobalt in this only two (at positions 1 and 5) of the four double bonds are linked to the central atom.
Anhydrite is 1–3% of the minerals in salt domes and is generally left as a cap at the top of the salt when the halite is removed by pore waters. The typical cap rock is a salt, topped by a layer of anhydrite, topped by patches of gypsum, topped by a layer of calcite. [ 8 ]
Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO 3 ·x(H 2 O). Two crystalline forms are known, the hemihydrate and the tetrahydrate, respectively CaSO 3 ·½(H 2 O) and CaSO 3 ·4(H 2 O). [2] All forms are white solids. It is most notable as the product of flue-gas desulfurization.
Ca 10−δ (PO 4) 6−δ (HPO 4) δ (OH) 2−δ → (1−δ) Ca 10 (PO 4) 6 (OH) 2 + 3δ Ca 3 (PO 4) 2. β-TCP can contain impurities, for example calcium pyrophosphate, Ca 2 P 2 O 7 and apatite. β-TCP is bioresorbable. The biodegradation of BCP involves faster dissolution of the β-TCP phase followed by elimination of HA crystals. β-TCP does ...
CA2, CA-2 or CA II may refer to : Carbonic anhydrase II, a human gene; United States Court of Appeals for the Second Circuit; California's 2nd congressional district; Hummel CA-2, an ultralight aircraft; California State Route 2; Ca II, a singly-ionized calcium that produces the H and K lines, and the calcium triplet lines in the spectrum of ...
