Explanation:
Detailed explanation-1: -2H2O2→2H2O+O2 is a disproportion reaction in which the oxygen undergone oxidation and reduction simultaneously.
Detailed explanation-2: -This coefficient of hydrogen is 2 and the coefficient of oxygen is here 1. Similarly, the coefficient of h 2 is here and the meaning of this coefficient is, we can say, 2 moles of h. 2 react with 1 mole of oxygen to produce 2 moles of water.
Detailed explanation-3: -Answer: The coefficients used to balance the given equation are 2, 1, 2. Therefore, option (D) is correct.
