What type of crystal is formed by calcium carbonate?
In laboratory only one form; in the nature many minerals has the formula CaCO3. See also: http://en.wikipedia.org/wiki/Calcium_carbonate and http://www.webmineral.com/cgi-bin/search/search.pl.
What minerals are in a limestone?
Limestone commonly predominantly contains Calcite and Aragonite which are the two crystal forms of Calcium Carbonate (CaCO3). It commonly also contains detrital clasts (broken pieces of other material) such as flint or chert which are silica. Some limestones also contain the mineral dolomite which is Calcium Magnesium Carbonate (CaMg(CO3))2.
What is the name given to a change which the calcium chloride crystal has undergone?
Ethalphy Change of Solution
Crystals of the ionic compound calcium fluoride have a different structure from that of the ionic compound calcium chloride?
The size of a chloride ion is much larger than the size of a fluoride ion. CaF2 arranges in the fluorite crystal structure , The holes where these fluoride ions fit in between the closely packed calcium cations are a certain size, which aren't big enough for chloride ions to fit into. Therefore, CaCl2 has to form a different crystal structure that allows for the larger anion size.
What mineral exhibits double refraction?
Double refraction is when you can see through a mineral and it shows two images instead of one. Calite is the mineral that exhibits it. I linked a great website for this kind of stuff below.
A light polariser consisting of a crystal of calcium carbonate?
Nicol prism
What is the name for a light polarizer consisting of a crystal of calcium carbonate?
Nicol Prism
What is the formula of dolomite?
Dolomite is a crystal of calcium magnesium carbonate, CaMg(CO3)2.
What is a raphide crystal?
needle-shaped crystals of calcium oxalate as the monohydrate or calcium carbonate as aragonite, found in more than 200 families of plants.
What is the active ingredient in chalk?
Chalk is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite which is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). It forms under relatively deep marine conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-organisms. Chalk can also refer to other compounds including magnesium silicate and calcium sulfate.
What is the chmical formula of marble?
Chemical formula for marble is CaCO3. Ca means calcium. C means carbon. O means oxygen. here it means 1 calcium, 1 carbon and 3 oxygen. They also call marble as calcium carbonate.

Is aragonite used in making flat screen tv?
Aragonite, a crystal form of calcium carbonate, is not widely used in manufacturing, as it is not stable at standard pressure or temperature. Calcium carbonate powder may be used in paints and adhesives, as well as a polishing agent for plastics and glass.

Why ammonium oxalate is added in calcium carbonte solution?
ammonium oxalate is added to calcium carbonate because in the reaction between the two a crystal is formed that contain the Ca+2 ion. This is useful because if you have a sample of sodium carbonate with an unknown molarity you can use the oxalate to extract this calcium and determine what the molarity of the unknown solution was
What is the main sediment of limestone?
The main sediment of limestone is calcium carbonate, which is primarily composed of the mineral calcite. It forms from the accumulation and compaction of the remains of marine organisms such as coral, shells, and skeletal fragments.
What is the chemical property of limestone?
a lime stone is sedimenty rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).
