The vapor pressures of so2(s) and so2(l) in the vicinity of the triple point are given by the equations, ln (p/torr) = 23.9812 - 4244.7/t and ln (p/torr) = 19.2453 - 3298.4/t, respectively, where t is absolute temperature. (i)determine from these equations the three phase change enthalpies, ∆subh°, ∆vaph° and ∆fush°. (ii)show your determination of the temperature and pressure at the triple point of sulfur dioxide. (iii)assume that the enthalpy of vaporization remains at the value determined here, and show your work to predict the standard boiling point temperature of so2.

Which statement correctly describes metallic bonds? a. they form when certain atoms lose electrons and other atoms gain electrons. b. they involve an attraction between anions and cations. they always involvpoth a metal and a nonmetal. d. they can only form between atoms of the same element. e. they form because electrons can move freely between atoms.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
