Monitoring data indicate that hexane is a widely occurring atmospheric pollutant. How is hexane used in low temperature thermometers? (6) Hexane is used as the liquid in low temperature … WebWhen the rod is placed close to a stream of water, the negative charges (electrons) in the polyethylene rod attract the partially positive hydrogen ends of nearby water molecules. This causes the water molecules to rotate so that their positive ends are closer to the rod than their negative ends.

Web10 feb. 2024 · The high solubility of ammonia is due to the presence of lone pairs at the nitrogen. It is attracted to hydrogen in the water molecule hydrogen bonds. This means the molecules will be soluble in a polar solvent such as water. In other words, the polarity of these molecules indicates that they dissolve in water. Web7 dec. 2024 · Water molecules experience much more attraction to one another than they do to hexane. Water molecules and hexane molecules cannot mix readily, and thus hexane is insoluble in water.
