Writing Chemical Equations:

An important skill that must be learned in chemistry is writing chemical equations, as these equations are representations of the chemical reactions between substances. A chemical equation consists of substances reacting on the left side and the products formed on the right side, with a right arrow inserted to show a chemical reaction taking place. The phases of the substances are included by writing them as subscripts contained in a parenthesis. For chemical reactions involving ions, superscripts are used and the number is usually placed before the charge (i.e. 2+, not +2).
