The vapor pressure of ethanol, C2H5OH, at 50.0 C is 233 mmHg, and its normal boiling point at 1 atm is 78.3 C. Calculate the vapH of ethanol.
Consider the following formulas for n-pentane and neopentane: CH3CH2CH2CH2CH3 -Pentane Both compounds have the same overall formula (C5H12, molar mass = 72.15 g/mol), yet n-pentane boils at 36.2C whereas neopentane boils at 9.5C. Rationalize the differences in the boiling points between these two nonpolar compounds.
Silane SiH4, phosphine (PH3), and hydrogen sulfide (H2S) melt at 185 C, 133 C, and 85 C, respectively. What does this suggest about the polar character and intermolecular attractions of the three compounds?
A fluorocarbon, CF4, has a critical temperature of 45.7 C and a critical pressure of 37 atm. Are there any conditions under which this compound can be a liquid at room temperature? Explain briefly.
Why do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.
ou seal a container half-filled with water. Which best describes what occurs in the container? Water evaporates until the air becomes saturated with water vapor; at this point, no more water evaporates. Water evaporates until the air becomes overly saturated (supersaturated) with water, and most of this water recondenses; this cycle continues until a certain amount of water vapor is present, and then the cycle ceases. The water does not evaporate because the container sealed. Water evaporates, and thou water evaporates and recondenses simultaneously and continuously. The water evaporates until it is eventually all in vapor form. stify your choice, and for choices you did not pick, explain what is wrong with them.
Consider the following data for xenon: Triple point: 121C, 280 torr Normal melting point: 112C Normal boiling point: 107C Which is more dense, Xe(s) or Xe(l)? How do the melting point and boiling point of xenon depend on pressure?
On the basis of intermolecular attractions, explain the differences in the boiling points of n butane (1 C) and chloroethane (12 C), which have similar molar masses.
Diethyl ether (CH3CH2OCH2CH3) was one of the first chemicals used as an anesthetic. At 34.6C, diethyl ether has a vapor pressure of 760. torr, and at 17.9C, it has a vapor pressure of 400. torr. What is the H of vaporization for diethyl ether?
