![**Lab Report Analysis**
**Recovered Products and Melting Points:**
- **Acetanilide Recovered:** 2.945 grams.
- **Melting Point of Acetanilide Product:** 234°C.
- **Benzil Recovered:** 0.98 grams.
- **Melting Point of Benzil:** 201.9°C.
**Questions to Be Answered in the Report:**
1. **Purity of Acetanilide Product:**
- Given the melting point of your acetanilide product, is it pure or impure? Explain your answer based on the melting point.
2. **Purity of Benzil Product:**
- Given the melting point of your benzil product, is it pure or impure? Explain your answer based on the melting point.
3. **Percentage Yield Calculations:**
- What is the % yield of acetanilide? % yield of benzil? Show your calculations.
4. **Determining Mixtures:**
- If I were to mix benzil and acetanilide together, would there be a way to determine that it was a mixture? Explain how to determine this.
5. **Effect of Drying Products on Melting Point:**
- If products were not allowed to dry, would that affect the melting point? In what way could you determine the effect?
**Note:**
In this image, there are no graphs or diagrams present. The questions are straightforward and relate to the evaluation of chemical purity, yield calculations, and procedural considerations in the determination of melting points.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5b975c54-4bb4-4418-8433-83ba3616f73a%2Fa1c86ce4-894b-4066-ae3a-f3167ba864b0%2Fxk3kb6_processed.jpeg&w=3840&q=75)
