The physical states of the reactants and products are specified. We use 's' for solids, 'l' for liquids and 'g' for gases. Sometimes 'aq' is used for aqueous - to represent that the given substance has been dissolved in excess of water. The strength of acid or base ..

A chemical equation gives information regarding the following: a) Molecular proportion of the reactants and the products. b) The relative mass of the reactants and the products. c) The relative volumes of gaseous substances - which may be reactants or products. The above can be illust..
