What is the chemical formula of olivine?

Answer 1

Obsidian is composed of silica and oxygen. It has the same composition of quartz, but has cooled too quickly to form crystals of any noticeable size, and is therefore a "glass". There are also minor impurities which will give obsidian different colors.

Answer 2

The general chemical formula for olivine is (Mg,Fe)2SiO4, where Mg represents magnesium, Fe represents iron, and Si represents silicon. The specific chemical composition can vary based on the relative amounts of magnesium and iron present in the mineral.

Answer 3

== == Similar to granite, with quartz, feldspar, mica, but technically not in mineral form because of a lack of crystallization.

Answer 4

Obsidian is a mixture, and thus does not have a chemical formula. Common components included SiO2, Al2O3, K2O, Na2O, and MgO

Answer 5

The Chemical Formula Of Olivine Is (Mg, Fe)2SiO4

Answer 6

Silicon oxide, with lesser amounts of Magnesium oxide and iron oxide.

Answer 7

Obsidian is a high Silica rock (SiO2) related to Acidic extrusive igneous rocks like Andesite and Rhyolite.

Answer 8

The principal component of obsidian is silicon dioxide.

Answer 9

SiO2 SiO2
