Given below are the temperatures at which two different liquids with the same empirical formula have a vapor pressure of 400 torr: Dimethyl ether -37.8oC
Ethanol 63.5oC
Which of the following statements is false?
Increasing the temperature will increase the vapor pressure of both liquids
Intermolecular attractive forces are stronger in ethanol than in dimethyl ether
The normal boiling point of dimethyl ether will be higher than the normal boiling point of ethanol
The reason that the temperature at which the vapor pressure is 400 torr is higher for ethanol than for dimethyl ether is that there is strong hydrogen bonding in ethanol

What is the number of moles in 15.0 g ash3?

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
