The normal melting points and boiling points of xenon are -112 deg. Celsius and -107 deg. Celsius, respectively. The Xe triple point is at -121 deg. Celsius and 282 torr, and its critical point is at 16.6 deg. C and 57.6 atm.
(A) Sketch the phase diagram for Xe, showing the 4 points given above and indicating the area in which each phase is stable.
(B) Will Xe(s) float on Xe(l)? Explain?
(C) If Xe gas is cooled under an external pressure of 100 torr, will it undergo condensation to a liquid or deposition to a solid? Explain.
What is the molecular formula of the compound 2,3-dimethyl-4-cyclopentyl-5-ethyldecane?
The structure for methyl orange in acid solution is not as simple as protonation of the amine nitrogen. In fact, protonation of one of the azo nitrogens occurs resulting in a new, conjugated system.
