Question

Уравняйте полуреакцию методом электронно-ионных уравнений. H2O2+.....=O2+H20

Answer 1

H2O2 + O3 = 2O2↑ + H2O
2O(-1)-2e=O2(0)     3    восстановитель

O3(0)+6e=3O(-2)    1    окислитель

Answer 2

Balancing the Half-Reaction Equation for H2O2 to O2 and H2O

To balance the half-reaction equation for the conversion of H2O2 to O2 and H2O, we can follow these steps:

1. Identify the Initial and Final Elements: - The initial element is H2O2, and the final elements are O2 and H2O.

2. Balance the Atoms Other Than Hydrogen and Oxygen: - In this case, the only atoms to balance are hydrogen and oxygen.

3. Balance the Oxygen Atoms: - There are 2 oxygen atoms in H2O2 and 2 oxygen atoms in O2, so the oxygen atoms are already balanced.

4. Balance the Hydrogen Atoms: - There are 2 hydrogen atoms in H2O2 and 2 hydrogen atoms in H2O, so the hydrogen atoms are already balanced.

5. Balance the Charge: - The charge on the left side of the equation should equal the charge on the right side.

6. Finalize the Equation: - Once all the atoms and charges are balanced, the equation is complete.

Let's balance the half-reaction equation for the conversion of H2O2 to O2 and H2O.

The balanced half-reaction equation is:

H2O2 → O2 + 2H2O

This equation is already balanced in terms of atoms and charge.
