Consider the following scenario, would say the figure is demonstrating: OOOO The less dense nexane ficats on top of the water completely soluble completely miscible completely immiscible London forces between hexane molecules Hydrogen bonds between water molecules Because the attractions between water and hexane molecules are different from the water water and hexane-nexane attractions the making causes a significant disruption of the structure of the liquid This creates a more ordered syste very tle mixing takes place, and the two lquids remain in the more disordered more probable unmired state Hexane and water do not mix water and hexane are completely miscible water and hexane are completely insoluble completely insoluble water and hexane are completely immiscible water and hexane are completely soluble

A typical aqueous sugar solution for making glazed donuts is about 1.5 molal. Given that the Kb of water is 0.51 oC/molal, calculate the boiling point of the sugar solution. Normal boiling point of water is 100 oC.   100 oC100.8 oC99.2 oC101.5 oC
