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.
== == Similar to granite, with quartz, feldspar, mica, but technically not in mineral form because of a lack of crystallization.
Obsidian is a mixture, and thus does not have a chemical formula. Common components included SiO2, Al2O3, K2O, Na2O, and MgO
The Chemical Formula Of Olivine Is (Mg, Fe)2SiO4
Silicon oxide, with lesser amounts of Magnesium oxide and iron oxide.
Obsidian is a high Silica rock (SiO2) related to Acidic extrusive igneous rocks like Andesite and Rhyolite.
The principal component of obsidian is silicon dioxide.
SiO2 SiO2

H2O is 2 hydrogens plus 1 oxygen and that makes the chemical formula for water.
The chemical formula for oxide is O2−
Any chemical formula; beans are not chemical compounds.
The chemical formula of Taconite is Fe3O4.
The mineral olivine is (Fe, Mg)2SiO4, or ferromagnesian silicate.
