A chemical equation is an expression which is representative of the nature and the amount of substances that are involved in a given reaction. For example if we consider the formation of water, this can be expressed through a chemical equation as follows:

2H2(g) + O2(g) → 2H2O (l)

The information which can be deduced is two-fold:

1) It gives a qualitative description about the state/phase of the reactants and products

2) It gives a quantitative description i.e. the mole ratios of the reactants and products or the reaction stoichiometry.

Ans: C) Chemical equations provide a qualitative and quantitative description of a reaction.
