Potassium superoxide reacts with moisture to form :

Answer

**Step-by-Step Solution:**

1. **Identify the Reactant**: The reactant in this scenario is potassium superoxide, which is represented by the chemical formula \( KO_2 \).

2. **Understand the Reaction**: Potassium superoxide reacts with moisture (water, \( H_2O \)). This reaction occurs in moist air, leading to the decomposition of potassium superoxide.

3. **Write the Reaction**: The reaction can be represented as follows:
\[ 4 KO_2 + 2 H_2O \rightarrow 4 KOH + 3 O_2 + 2 H_2O_2 \]
Here, potassium superoxide decomposes into potassium hydroxide (\( KOH \)), oxygen gas (\( O_2 \)), and hydrogen peroxide (\( H_2O_2 \)).

4. **Balance the Reaction**:
- Count the number of each type of atom on both sides of the equation.
- Adjust coefficients to ensure that the number of atoms for each element is the same on both sides.
- After balancing, the final balanced reaction is:
\[ 4 KO_2 + 2 H_2O \rightarrow 4 KOH + 3 O_2 + 2 H_2O_2 \]

5. **Conclusion**: The products formed when potassium superoxide reacts with moisture are potassium hydroxide (\( KOH \)), oxygen gas (\( O_2 \)), and hydrogen peroxide (\( H_2O_2 \)).
