All chemical changes are accompanied by chemical reactions. These reactions are described in sentence form with the help of chemical equations in terms of symbols and formulae of substances involved. Initially, the equation is in a skeletal form which is then balanced so that the total number of reactant species is the same as that of product species.
Why should a chemical equation be made molecular?
Chemical equation:
Explanation:
Hence, to fulfill the condition of the law of conservation of mass and as most gases exist in the molecular form a chemical equation must be made molecular.
