A balanced chemical equation gives the following information:

• The chemical species reacting with each other.
• The products formed in the chemical reaction.
• The number of molecules of the reactant reacting.
• The number of molecules of product formed.
• The physical state of the reactants and the products like:
  • (s) - Solid
  • (l) - Liquid
  • (g) - Gas
  • (aq) - Aqueous state
• The type of reaction:
  • Combination
  • Decomposition (thermal or by light)
  • Diplacement (Single or Double)
  • Redox
• Exothermic (Heat evolved) or endothermic (Heat absorbed).
• The reaction conditions, like acidic or alkaline.
