When benzene freezes at 5.5°C its density changes from 0.879 g cm−3 to 0.891 g cm−3. Its enthalpy of fusion is 10.59 kJ mol−1. Estimate the freezing point of benzene at 1000 atm. Answer= ???. ??
Compound Chemical formula Hvap (kJ⋅mol−1) Boiling point (K) Hfus(kJ⋅mol−1) chloromethane CH3Cl 21.40 249.06 6.43 water H2O 40.65 373.15 6.01 hydrogen sulfide H2S 18.67 213.60 18.67 1. Trouton's rule states that the molar enthalpy of vaporization of a liquid that does not have strong molecular interactions such as hydrogen bonding or ion‑ion attractions is given by Hvap=(85 J⋅K-1⋅ mol-1)Tb Where Tb is the normal boiling point of the liquid in kelvins. Apply Trouton's rule to estimate the value of Hvap for these compounds: chloromethane: Hvap= ? kJ/mol water: Hvap= ? kJ/mol hydrogen sulfide: Hvap = ? kJ/mol

The vapor pressure of ethanol is 24.1 Torr at 10C and 44.0 Torr at 20C. Calculate the enthalpy of vaporization of ethanol over this temperature range.
A geochemist in the field takes a 9.0 mL sample of water from a rock pool lined with crystals of a certain mineral compound X. He notes the temperature of the pool, 15. C, and caps the sample carefully. Back in the lab, the geochemist first dilutes the sample with distilled water to 400. mL.. Then he filters and evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 0.045 g. Using only the information above, can you calculate the solubility of Xin water at 15.° C7 If you said yes, calculate it.
