Based upon the intermolecular forces present, rank the following substances according to the expected boiling point for the substance. Rank from highest to lowest boiling point. To rank items as equivalent, overlap them. HCl, NaCl, N2, H2O
Assume that the partition coefficient, K, for partitoning of compound A between diethyl ether and water is 3; that is, A preferentially partitions into ether.
The energy from condensing steam water is used to melt ice at 0 degrees Celsius. How much ice can be melted by condensing 1.0 kg of H2O vapor? (Delta H fus of ice= 6.01 kj/mol) (Delta H vap of water = 40.7 kj/mol)
