To determine which student correctly labeled the substances as mixtures or pure substances, we need to classify each of the given substances:
1. **Soil** - A mixture; it contains various organic and inorganic materials.
2. **Gold metal** - A pure substance; it is a single element.
3. **Copper wire** - A pure substance; made of copper, which is also a single element.
4. **Table salt** (sodium chloride, NaCl) - A pure substance; it is a compound made up of sodium and chlorine in a fixed ratio.
Now, let's summarize the classification:
- **Soil**: Mixture
- **Gold metal**: Pure substance
- **Copper wire**: Pure substance
- **Table salt**: Pure substance
Since I do not have access to the replies of students L, M, N, and O, I cannot definitively say which student labeled them correctly without the respective answers listed in the table. Please provide the labeling from the students, and I can help determine which student is correct.
