The chemical formula for most glass is SiO2. Commonly referred to as sand, it's the main ingredient in the most common forms of glass. In it's natural state, silicone dioxide (sand) has a crystalline structure For simple molecules, a condensed (or semi-structural) formula is a type of chemical formula that may fully imply a correct structural formula. For example, ethanol may be represented by the condensed chemical formula CH 3 CH 2 OH, and dimethyl ether by the condensed formula CH 3 OCH 3

There are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other. Created by Sal Khan What is a Chemical Formula? The chemical formula is a symbolic representation of the available compositions of various elements present in an atom or molecule. For this symbolic representation, we use numbers, parenthesis, chemical element symbols. It is different from structural formulas The chemical formula of an element is a statement of the composition of its molecule in which symbol tells us the element and the subscript tells us how many atoms are present in one molecule. One molecule of hydrogen element contains two atoms of hydrogen, therefore, the formula of hydrogen is H 2 Borax formula, also known as sodium borate formula, sodium tetraborate formula or disodium tetraborate formula is explained in this article.
