Complete the following reactions
(i) `O_(2)^(2-)+H_(2)O rarr` (ii) `O_(2)^(-) +H_(2)O rarr`

Explanation

To complete the reactions given in the question, we will analyze each reaction step by step.

### Reaction (i): \( O_2^{2-} + H_2O \rightarrow \)

1. **Identify the Ion**: The ion \( O_2^{2-} \) is known as the peroxide ion.
2. **Reaction with Water**: When the peroxide ion reacts with water, it produces hydroxide ions and hydrogen peroxide.
3. **Write the Balanced Equation**:
\[
