#46: I dont understand why C is true. The answer choice states that Hydrogen bonding will cause the solid-liquid line to be skewed to the left in a phase of P vs. T. My reasoning: Hydrogen bonding increases solubility or like dissolves like , therefore wouldnt the line shift to the right in the liquid phase. I did not full grasp the destroyer solution. Can someone please clarify. #56: Why would the Eo for for Cr be positive if it is being oxidized. I thought the more positive Eo indicates being reduced.??? #64: This problem deals with vapor pressure. Now please correct me if I am wrong but a substance boils when the vapor pressure equals atmospheric presssure. This problem states that when KOH is dissolved in water, we see a decrease in the vapor pressure of the solution. My reasoning: When KOH dissolves in water doesnt that increase the boiling point. inturn wouldnt this mean a higher vapor pressure, because the solution will now boil at a higher temperature?? very confused.
