In geology, carbonates are a class of sedimentary rocks compose primarily of carbonate minerals. Two major types are limestone, which is composed of calcite or aragonite (different crystalline forms of CaCO3) and dolostone, which is composed of the mineral dolomite (CaMg(CO3)2).

‘Snowball Earth’—a problem for the supposed origin of multicellular animals by Michael J. Oard Many uniformitarian scientists believe that about five major periods, and several short periods, of glaciation have occurred on Earth. 1 In the evolutionary time scale, these ice age periods sometimes lasted several hundred million years and extended back 2–3 billion years ago.

6/10/2014· Some statements about carbonates in Steve Anchell, The Darkroom Cookbook, 3rd edition, Focal Press, 2008, are not clear at all for me: First problem: "Potassium carbonate is far more soluble than sodium carbonate, hence its use in highly concentrated solutions.
6/8/2017· The Supreme Court ban on the use of antimony, lithium, mercury, arsenic and lead in the manufacture of firecrackers to prevent air pollution has turned the focus on what chemicals are used to
The Nuffield Data Book quotes anyhydrous beryllium sulphate, BeSO 4, asinsoluble(I haven''t been able to confirm this from any other source), whereas the hydrated form, BeSO4.4H2O is soluble. (The Data Books agree on this - giving a figure of about 39 g dissolving in 100 g of water at room temperature.)
The products are highly soluble, and enter solution. This process dissolves limestone, yielding open cavities. Since all rainwater is slightly acidic exposed carbonates are etched by solution. This ultimately creates cavities that can be the size of large buildings.

Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precarian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
It is more solvent soluble, has better resin compatibility, is less volatile, and provides a degree of stabilization that is significantly better than other UV absorber based on benzotriazole or benzophenone, which are commercially available in the market.

Yet, when preparation of water-soluble aspirin compositions is desired, it is impossible to avoid the use of alkaline compounds. This is because the only known method of converting aspirin into soluble form is by means of reacting it with an alkaline compound to form the soluble salt of aspirin.
17/8/2020· Solid solution, mixture of two crystalline solids that coexist as a new crystalline solid, or crystal lattice. The mixing can be accomplished by coining the two solids when they have been melted into liquids at high temperatures and then cooling the result to form
Normally glucose is virtually absent from urine .the renal threshold for glucose ranges from 160-200mgm/dl depending on the individual .that is blood sugar must rise to its renal threshold before glucose will appear in urine. When glucose is present in urine it is called glysosuria.other less important sugar that may appear in urine are lactose galactose pentose which may give false positive
