Burning magnesium continues to burn in nitric oxide, while burning sulphur is extinguised. Give reason.

Explanation

### Step-by-Step Solution:

1. **Understanding the Reaction of Magnesium with Nitric Oxide:**
- When magnesium burns, it reacts with oxygen to form magnesium oxide (MgO). This reaction is highly exothermic, meaning it releases a significant amount of heat.
- The reaction can be represented as:
\[ 2Mg + O_2 \rightarrow 2MgO + \text{Heat} \]
