please answer ALL of the dollowing, thank you

6. Ammonia is found to be more soluble in water than phosphorus trichloride, even though ammonia and phosphons trichloride have very similar Lewis stractures. Why the difference? What does having similar Lewis structures have to do with the solubility, if any, between ammonia and phosphorus trichloride in wate? Chemical Phases and Vaper Pressure: 7. Suppose you heat up an unknown substance which bubbles up apon teaching a temperature of 18.8C. At what temperature would you expect the vapor pressure of the substance to be 593 mmHg if the unknown substance has a H10=42kJ/mol ? 8. If the vapor pressure of a liquid is incressed, what is the effect on the temperature? 9. The vapor pressure of molecule X at 22.3C is 70mmmg.Findthevaporpressureofthismoleculeat 844C.Hi,=28kl/mol,R=8.314J/molK
