A student adds \(10 \text{ mL}\) of liquid ethanol (\(\text{CH}_3\text{CH}_2\text{OH}\)) to a test tube containing \(10 \text{ mL}\) of distilled water (\(\text{H}_2\text{O}\)). In a second test tube, the student adds \(10 \text{ mL}\) of liquid hexane (\(\text{C}_6\text{H}_{14}\)) to \(10 \text{ mL}\) of distilled water. Both test tubes are capped, thoroughly shaken, and allowed to stand at \(25\ ^\circ\text{C}\). Which of the following best predicts the outcome observed in the test tubes and provides the correct chemical explanation?
