Answer

Balanced chemical equation is symbolic representation of a chemical reaction. It provides the following information, which is useful in solving problems based on chemical equations:
  • It indicates the number of moles of the reactants involved in a chemical reaction and the number of moles of the products formed.
  • It indicates the relative masses of the reactants and products linked with a chemical change, and
  • It indicates the relationship between the volume/s of the gaseous reactants and products, at STP.
Hence, balanced chemical equation is useful in solving problems based on chemical equations.
