Ozonised oxygen mixture when condensed which is first liquified. 

Options

A. `O_(2)`
B. `O_(3)`
C. Both are at same time
D. Both are never condensed

Answer

To solve the question regarding the condensation of ozonized oxygen mixture, we can break down the process into clear steps:

### Step-by-Step Solution:

1. **Understanding Ozonized Oxygen**:
- Ozonized oxygen refers to a mixture of oxygen (O2) and ozone (O3). Ozone is a triatomic molecule composed of three oxygen atoms.

2. **Starting with Liquid Oxygen**:
- The process begins with liquefied oxygen (O2). Liquid oxygen is obtained by cooling gaseous oxygen at very low temperatures.

3. **Formation of Ozone**:
- When the liquefied oxygen is subjected to an electrical discharge or ultraviolet light, it can undergo a reaction to form ozone. The reaction can be represented as:
\[ 3O_2 \xrightarrow{UV \text{ light or electrical discharge}} 2O_3 \]
- This indicates that three molecules of diatomic oxygen can produce two molecules of ozone.

4. **Condensation of the Ozonized Oxygen Mixture**:
- When the ozonized oxygen mixture is further condensed, it means that the temperature and pressure conditions are adjusted to convert the gaseous mixture into a liquid state.

5. **Final Product**:
- Upon further condensation, the primary product formed is ozone (O3). Therefore, the ozonized oxygen mixture, when condensed, will yield liquid ozone.

### Conclusion:
The final product when the ozonized oxygen mixture is condensed is ozone (O3).
