I'm going over a study guide for a test. The correct answers are listed. However I have highlighted the ones I do not understand. Please explain in detail! Much appreciated.
Heat of sublimation can be approximated by adding together, _and_- . A) heat of fusion, heat of condensation B) heat of fusion, heat of vaporization C) heat of freezing (solidification), heat of condensation D) heat of freezing (solidification), heat of vaporization E) heat of deposition, heat of vaporization 10hlaced n a contane of non, the agon pontaneoudies hrugbout tenceon because A) of the large attractive forces between argon and neon atoms B) of hydrogen bonding C) a decrease in energy occurs when the two mix Di the dispersion of argon atoms produces an increase in disorder E) of solvent-solute interactions 11) Formation of solutions where the process is endothermic can be spontaneous provided that A) they are accompanied by another process that is exothermic B) they are accompanied by an increase in order . D) the solvent is a gas and the solute is a solid E) the solvent is water and the solute is a gas 12) The principal reason for the extremely low solubility of NaCl in benzene (C6H6) is the Analyze: lonic compounds tend to form ion-dipole interactions being dissolved and dissociated. That is why are soluble in polar solvents. Benzene is non-polar, so solvation of Na and Cl- in it is weak. A) strong solvent-solvent interactions B) hydrogen bonding in C6H6 C) strength of the covalent bond in NaC DI weak solvation of Nat and Cby CGHs E) increased disorder due to mixing of solute and solvent 13) The concentration of CO2 in a soft drink bottled with a partial pressure of Co2 of 4.0 atm over th at 25â is 12x 1o-1 M. The Henry's law constant for CO2 at this temperature is Analyze: k can be calculated from Henry's law: S kP A1 3.0 x 10-2 mol/L-atm .
