  • 2H₂O₂ gives 2H₂O and O₂ .
  • When 4H₂O₂ is taken 2O₂ is produced, this can be simply explained by balancing the entire equation.
  •      4H₂O₂   -------->   4H₂O  +  2O₂ .
  • On balancing the equation when taking 4H₂O₂ we get 4 H₂O and 2O₂.
  • Where H₂O₂ is called hydrogen peroxide which is a unstable compound, and H₂O is water and O₂ is oxygen gas.

Result: 4H₂O₂ will produce 2O₂ .
