Barium fluoride is BaF2.
Sodium oxides are Na2O, Na2O2, NaO2.
The formula for barium fluoride is BaF₂, for sodium oxide is Na₂O, for iron sulfate is FeSO₄, and for ammonium sulfate is (NH₄)₂SO₄. Each formula represents the composition of the respective compound, indicating the elements and their ratios.
This element is sodium - a layer of sodium oxide is formed on the surface of the metal.
Barium oxide is formed from barium and oxygen.
Barium Oxide
Barium can form both barium peroxide (BaO2) and barium oxide (BaO) depending on the conditions. Barium peroxide is formed when barium reacts with oxygen in excess. Barium oxide is commonly formed when barium reacts with oxygen in limited supply or at high temperatures.
Lithium chloride, barium oxide, sodium nitride, lead (II) sulphate
BaO is Barium Oxide. Barium Oxide is used in the making of glass.
The compound CrO is chromium(II) oxide, containing chromium and oxygen ions. BaF2 is barium fluoride, consisting of barium and fluoride ions. Cl is a single Cl atom of chlorine. So, CrO and BaF2 are compounds, while Cl is an element.
Barium oxide
Barium oxide is commonly known as baria.
Carbon Dioxide is the compound that contains covalent bonds. It is composed of one carbon atom covalently bonded to two oxygen atoms. Sodium chloride, Calcium Oxide, Barium Bromide, and Cesium Oxide contain ionic bonds.
LiCl is lithium chloride. BaO is barium oxide. Na3N is sodium nitride. PbSO4 is lead II sulfate.
