Final answer:
To balance the given equation for the half reaction that occurs in acidic solution, follow the steps to balance the atoms and charges.
Step-by-step explanation:
To balance the given equation for the half reaction that occurs in acidic solution:
Mn³⁺ → MoO₂²⁺
We can follow the following steps:
- Balance the atoms other than O and H
- Balance the O atoms by adding H₂O molecules
- Balance the H atoms by adding H⁺ ions
- Balance the charges by adding electrons
- Equalize the number of electrons in both half-reactions
- Add the two balanced half-reactions together
The balanced equation for the half reaction in acidic solution is:
Mo⁺³ + 4H⁺ + e⁻ → MoO₂ ²⁺ + 2H₂O
