Описание к видео 17.6b | Balance the equation in an basic solution: O2(g) + Mn(OH)2(s) → MnO2(s)

"Balance the equations below assuming they occur in a basic solution.
O2(g) + Mn(OH)2(s) → MnO2(s)"
Here is the balanced equation for the reaction in a basic solution:

```
O2(g) + 2Mn(OH)2(s) → 2MnO2(s) + 2H2O(l)
```

Steps to balance the equation:
1. *Write the half-reactions* for oxidation and reduction:
Oxidation: Mn(OH)2 → MnO2
Reduction: O2 → H2O
2. *Balance the atoms* in each half-reaction.
3. *Balance oxygen atoms* by adding OH− or H2O as needed.
4. *Balance hydrogen atoms* by adding OH− as needed.
5. *Balance the charges* by adding electrons (e−) to the half-reactions.
6. *Multiply the half-reactions* to make the number of electrons equal.
7. *Add the half-reactions* together and simplify if necessary.
