How to balance a modern chemical equation. The Law of Conservation of Mass. Return to Equations Menu. Chemical equations give information in two major areas. First, they tell us what substances are reacting (those being used up) and what substances are products (those being made).Second, the coefficients of a balanced equation tell us in what ratio the substances react or are produced.This last point has practical consequences whenever chemicals react.irst, they tell us what substances are reacting (those being used up) and what substances are products (those being made).
