The molecular formulas for iron oxide, sodium chloride, and silicon chloride are as follows:
Iron Oxide: Iron oxide is a compound formed by the combination of iron and oxygen. However, there are several different forms of iron oxide with varying chemical compositions. The most common forms are iron(II) oxide (FeO), iron(III) oxide (Fe2O3), and iron(II,III) oxide (Fe3O4). Iron(II) oxide has a stoichiometric ratio of 1:1 for iron and oxygen, iron(III) oxide has a ratio of 2:3, and iron(II,III) oxide has a ratio of 1:1.5.
Sodium Chloride: Sodium chloride is commonly known as table salt and has the chemical formula NaCl. It consists of one sodium atom (Na) and one chlorine atom (Cl) held together by ionic bonds.
Silicon Chloride: Silicon chloride can refer to several different compounds with varying compositions. The most common form is silicon tetrachloride, which has the chemical formula SiCl4. It consists of one silicon atom (Si) bonded to four chlorine atoms (Cl).
