The equations from the two previous pages 2K + Cl 2 2KCl 4Li + O 2 2Li 2 O still require state symbols to be complete.. Subscripts appear at or below the baseline, while superscripts are above.Subscripts and superscripts are perhaps most often used in formulas, mathematical expressions, and specifications of chemical . The intended use when these characters were added to Unicode was to allow chemical and algebra formulas and phonetics to be written without markup, but produce true superscripts and subscripts. If a subscript is not present, it just means there is only one of that element. A subscript is text formatting set below the normal text baseline (as pictured above on the right) and is also often used in mathematical equations and chemical formulas. In chemical formulas the number of atoms in a molecule is written as a subscript, so we write H2O for water which has two atoms of hydrogen for each one of oxygen. a chemical equation that does not indicate the relative amounts of reactants and products.
