  • Balancing Chemical Equations.

  • The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction.

  • I will break the law.

  • I will create mass.

  • Creation of mass.

  • Creation of mass.

  • No extra mass allowed.

  • New creation of mass is not allowed.

  • Deduction of mass.

  • No deduction of mass allowed.

  • In a chemical reaction, mass cannot be created, mass cannot be destroyed.

  • In a reaction, number of atoms should be same.

  • Before and After.

  • Example.

  • Hydrogen plus Nitrogen is equal to Ammonia.

  • Here, 2 is the subscript of hydrogen and nitrogen.

  • We need to balance the number of atoms on both the sides.

  • Reactants and Product.

  • 2 Hydrogen atoms.

  • 3 Hydrogen atoms.

  • 2 Nitrogen atoms.

  • 1 Nitrogen atom.

  • 2 Nitrogen atoms.

  • 1 Nitrogen atom.

  • I need to balance nitrogen atoms on both the sides.

  • 2 Ammonia atoms.

  • 2 Hydrogen atoms.

  • 3 Hydrogen atoms.

  • 3 Hydrogen atoms.

  • 6 Hydrogen atoms.

  • I need to balance hydrogen atoms on both the sides.

  • 3 Hydrogen atoms.

  • Perfectly balanced chemical equation.

  • Hydrogen plus Nitrogen equals Ammonia.

  • The End.
