Question

How can a chemical equation be made more informative?

Answer 1

By the addition of subscripts, (s), (l), (g), that identify the state of reactant or product; by the addition of thermodynamic parameters.

Explanation:

Quite clearly, inclusion of the physical states of reactants and products is desirable. So too is the inclusion of thermodynamic parameters, `DeltaH`, `DeltaS`, `K_(eq)`, etc. Balanced equations (LHS = RHS) are absolutely essential.
