the difference in the boiling point of this soln compared to pure water equals Kb times m, where Kb is the boiling point constant(0.512 for water) and m is the molality of the soln.\nso the answer si 100.512 degrees C.

OK...You can start with the equation of DG (I'm using D instead of writing "delta").\n\nDG = DH -TDS  You've seen that equation, right?  OK..Since the boiling point of water is 100 degreed C at 1 atm pressure, we are really talking about an equilibrium situation.  So, DG= 0.\n\nConsequently, DH = TDS.  \n\nSince you know DH and you know T (in Kelvin), you can calculate DS.  Make sure that you convert DH into Joules (instead of kilojoules) before you finish the problem.

The first answer is correct. Here is a page to help you figure out the altitude. You punch in the elevation and it will tell you the boiling point.

I would say CH2O2 (I'm assuming you mean formic acid, not dioxirane), CH3CO2H, and water.  \n\n"Important" is a tough word here, as all of these compounds can participate in h-bonding to varying degreees, with water being the strongest and CH2F2 being the weakest.  That said, strong hydrogen bonding gives rise to many of the nifty properties of water and in all three cases the h-bonding is powerful enough to raise the boiling points to be significantly higher than what you would expect based on molecular weight.

The boiling point series for short alcohols is dominated by hydrogen bonding.  That's where the H on the hydroxyl group (OH)  on one molecule is attracted to the O on a nearby molecule.\nEven tough "normal alcohol" (I imagine you mean n-butanol from the context of your question) is just as heavy, it will have a higher boiling point because its structure makes hydrogen bonding easier.  It is basically alike to a bunch of strings with the magnets on their ends with nothing to impede the other strings from glomming on.\nTert-butanol, on the other hand, is like a bunch of knotted strings with magnets at the base of the knot.  The hydroxyl group on these molecules are not all that available for their neighboring molecules to find and be attracted to.  This is called "steric hinderance" and is more a physical and spatial consideration than a chemical phenomenon.

The order of elution will depend upon the mobile phase of the column.  If one uses a boiling point column then, naturally, they will elute in the order of their relative boiling points with the lowest boiling point eluting first.

i dont really feel like thinking about the question but this should help\nuse the fact that the boiling point is when the vapor pressure equals the atmospheric pressure \nso at 139.6C the vapor pressure is 1 atm, perhaps you can just set up a ratio, but since that delta h is there u need to use something that involves that \nsrry that im feeling lazy
