The various ways in which a chemical equation can be made more informative are : (i) By indicating the physical states of the reactants and products. Example: Solid state is indicated by the symbol (s).

(ii) By indicating the heat changes taking place in the reaction. For Example: An exothermic reaction is indicated by writing “+Heat” or “+Heat energy” or “+Energy” on the products side of an equation.

(iii) By indicating the “conditions” under which the reaction takes place.

Example: Delta stands for heat which is written on the arrow sign in the equation.
