**Situation Analysis:**

An unknown liquid is added to a beaker of water. After a few minutes, you observe that the unknown liquid is floating on top of the water in a separate layer.

**Task:**

Explain what type of compound the unknown liquid is, and how you know.

**Explanation:**

In this scenario, the unknown liquid forms a distinct layer above the water, indicating that it is less dense than water. Additionally, the separation suggests that the unknown liquid is likely non-polar, as it does not mix with the polar water molecules. Therefore, the unknown liquid is probably a non-polar compound, such as oil.

**Evidence:**

- **Density:** Since the unknown liquid floats, it is less dense than water.
- **Polarity:** The inability to mix with water indicates the liquid is non-polar, as polar and non-polar substances generally do not mix well.

Understanding these principles helps identify the characteristics of unknown substances in chemical experiments.

Expert Solution

Step 1 Theory

Like dissolves like.

It means polar solvents are miscible in polar solvents and non-polar solvents are miscible in non-polar solvents.

Non-polar solvent are not miscible in polar solvents. Non-polar solvents form a separate layer in polar solvents.
