A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.

Chemical formulas and other symbols are used to indicate the starting materials, or reactants, which by convention are written on the left side of the equation, and the final compounds, or products, which are written on the right. An arrow points from the reactant to the products. The equation for this reaction is even more informative when written as follows:. Equation 4. The abbreviations are s for solid, l for liquid, g for gas, and aq for an aqueous solution, a solution of the substance in water.
