Question
A solution is prepared that is initially 0.39 M in methylamine (CH₃NH₂), a weak base, and 0.41 M in methylammonium chloride (CH₃NH₃Cl). Complete the reaction table below, so that you could use it to calculate the pH of this solution.

Use \( x \) to stand for the unknown change in \([\text{OH}^-]\). You can leave out the \(M\) symbol for molarity.

### Reaction Table:

|                    | [CH₃NH₂] | [CH₃NH₃⁺] | [OH⁻] |
|--------------------|----------|-----------|-------|
| **Initial**        |          |           |       |
| **Change**         |          |           |       |
| **Final**          |          |           |       |

### Diagram Explanation:
- The table includes three columns, each representing the concentration of different components ([CH₃NH₂], [CH₃NH₃⁺], and [OH⁻]).
- There are three rows for initial concentration, change in concentration, and final concentration of each component.
- An empty square is included next to the diagram, likely for calculation purposes.
- A box with tools is present nearby, showing symbols for entering values or calculations associated with \( x \).
