farmula de dolamite

Dolemite is a 1975 American blaxploitation crime film, and is also the name of its principal character, played by Rudy Ray Moore, who co-wrote the film and its soundtrack.
Dolomita ou dolomite [1] (assim denominada em homenagem ao geólogo francês Déodat de Dolomieu [2] [3]) é um mineral de carbonato de cálcio e magnésio CaMg(CO 3) 2, muito abundante na natureza na forma de rochas dolomíticas, utilizado como fonte de magnésio, sobretudo para a fabricação de materiais refratários.
Dolomit este un mineral din grupa carbonaților anhidri, frecvent întâlnit în natură.Mineralul cristalizează în sistemul trigonal-romboedric, având formula chimică CaMg(CO 3) 2, dominând cristalele romboedrice, sau agregatele masive de culoare albă cenușie cu variante de culoare ce pot fi până la brun deschis.Are o duritate relativ mică, între 3,5 și 4 cu o densitate de 2,9 g/cm³.
Le groupe de la dolomite est composé de minéraux de formule générale AB(CO 3) 2 où A peut être une atome de calcium, de baryum et ou de strontium. B peut être le fer , le magnésium , le zinc et ou le manganèse , avec la même structure cristalline.

What Is the Chemical Formula for Limestone? ... Calcium carbonate is commonly known as calcite,and calcium-magnesium carbonate is commonly known as dolomite. In nature, limestone deposits are very rarely composed of pure calcite or pure dolomite, although such deposits have been found.
"Dolomite" is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite; and, 2) as the name of a rock known as dolomite, dolostone, or dolomite rock. This page is about the mineral dolomite.
Dolomite, which is named for the French mineralogist Deodat de Dolomieu, is a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick. They are found all over the world and are quite common in sedimentary rock sequences.
Dolomite is an important component on Earth, including in structures such as the Dolomite mountains Which brings us to a second point - rocks rock, but minerals rule.

Calcium carbonate is an exceptional compound. The chemical formula CaCO 3 represents a raw material that exists everywhere in nature – whether dissolved in rivers and oceans, melted as "cold" carbonatite lava and solidified as a mineral, dripstone or as a parent material for whole mountain ranges..
