Magnesium burns in the atmoshphere of the following gases?

Options

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

Explanation

To determine in which gases magnesium burns, we will analyze each gas provided in the question: Carbon Dioxide (CO2), Nitrous Oxide (N2O), Nitrogen (N2), and Sulfur Dioxide (SO2).

### Step-by-Step Solution:

1. **Magnesium and Carbon Dioxide (CO2)**:
- When magnesium is introduced to carbon dioxide, it reacts to form magnesium carbonate (MgCO3).
- The reaction can be represented as:
\[ 2Mg + CO2 \rightarrow MgCO3 \]
- Therefore, magnesium burns in the presence of carbon dioxide.

2. **Magnesium and Nitrous Oxide (N2O)**:
- Nitrous oxide contains oxygen, which allows magnesium to react and form magnesium oxide (MgO) while liberating nitrogen gas (N2).
- The reaction is:
\[ 2Mg + N2O \rightarrow 2MgO + N2 \]
- Hence, magnesium can also burn in the presence of nitrous oxide.

3. **Magnesium and Nitrogen (N2)**:
- Although nitrogen is generally inert, the high temperature produced by burning magnesium allows it to react with nitrogen.
- The reaction forms magnesium nitride (Mg3N2):
\[ 3Mg + N2 \rightarrow Mg3N2 \]
- Thus, magnesium burns in nitrogen as well.

4. **Magnesium and Sulfur Dioxide (SO2)**:
- Sulfur dioxide contains oxygen, which allows magnesium to react and form magnesium oxide (MgO) while liberating sulfur (S).
- The reaction can be represented as:
\[ Mg + SO2 \rightarrow MgO + S \]
- Therefore, magnesium burns in the presence of sulfur dioxide too.

### Conclusion:
Magnesium burns in the atmosphere of all the given gases: Carbon Dioxide (CO2), Nitrous Oxide (N2O), Nitrogen (N2), and Sulfur Dioxide (SO2). Thus, the correct answer is that magnesium burns in all of these gases.
