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

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

The principal component of obsidian is silicon dioxide.

Answer 8

SiO2 SiO2
