<P> Chemical equations are used to graphically illustrate chemical reactions . They consist of chemical or structural formulas of the reactants on the left and those of the products on the right . They are separated by an arrow ( → ) which indicates the direction and type of the reaction ; the arrow is read as the word `` yields '' . The tip of the arrow points in the direction in which the reaction proceeds . A double arrow ( ⇌ ) pointing in opposite directions is used for equilibrium reactions . Equations should be balanced according to the stoichiometry , the number of atoms of each species should be the same on both sides of the equation . This is achieved by scaling the number of involved molecules ( A , B , C ( \ displaystyle ( \ ce ( A , B , C ) ) ) and D ( \ displaystyle ( \ ce ( D ) ) ) in a schematic example below ) by the appropriate integers a , b , c and d . </P>
