Answer

To answer the question regarding what gun powder is a mixture of, we can break down the components typically found in gun powder.

### Step-by-Step Solution:

1. **Understanding Gun Powder Composition**: Gun powder, also known as black powder, is a traditional explosive that has been used for centuries. It is primarily composed of three key ingredients.

2. **Identifying the Ingredients**:
- **Potassium Nitrate (KNO₃)**: This is the primary oxidizer in gun powder. It provides the oxygen needed for the combustion of the other components.
- **Charcoal (C)**: Charcoal acts as the fuel in the mixture. It burns quickly and contributes to the explosive reaction.
- **Sulfur (S)**: Sulfur is also included in gun powder as it helps to lower the ignition temperature and increases the speed of combustion.

3. **Combining the Components**: When potassium nitrate, charcoal, and sulfur are mixed together in the right proportions, they create gun powder.

4. **Conclusion**: Therefore, gun powder is a mixture of potassium nitrate, charcoal, and sulfur.

### Final Answer:
Gun powder is a mixture of potassium nitrate, charcoal, and sulfur.
