Greenhouse gas other than `CO_(2)` is

Options

A. `H_(2)`
B. `N_(2)O`
C. `O_(2)`
D. `SO_(2)`

Answer

To answer the question "Greenhouse gas other than CO₂ is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Greenhouse Gases**:
- Greenhouse gases are substances in the atmosphere that can trap heat. They are responsible for the greenhouse effect, which warms the Earth's surface.

2. **Identify the Major Greenhouse Gases**:
- The most common greenhouse gas is carbon dioxide (CO₂). However, there are several other greenhouse gases that also contribute to the greenhouse effect.

3. **List Other Greenhouse Gases**:
- Some of the significant greenhouse gases other than CO₂ include:
- Methane (CH₄)
- Nitrous oxide (N₂O)
- Chlorofluorocarbons (CFCs)
- Water vapor (H₂O)

4. **Evaluate the Options**:
- If given multiple-choice options, identify which of them are greenhouse gases. For example, if the options include:
- A) Methane
- B) Nitrous oxide
- C) Chlorofluorocarbons
- D) Hydrogen
- The correct answers would be A, B, and C, as they are all greenhouse gases.

5. **Choose the Correct Answer**:
- If the question specifically asks for one greenhouse gas other than CO₂, you can choose any from the list above. For example, if the question specifies "other than CO₂," you could select "Nitrous oxide" as a valid answer.

### Final Answer:
- A greenhouse gas other than CO₂ is **Nitrous oxide (N₂O)**.
