When a molecule forms a hydrogen-bonded dimer as shown in your lab manual on pg 162 or is an electrolyte, you need to account for Van't Hoff factors. For the dimer shown in manual
If the solubility of a gas is 7.5 g/L at 404 kPa pressure, what is the solubility of the gas when the pressure is 202 kPa?
how does direct current break apart water molecule? Does the DC current fill the outer shell full of electrons making a weaker attraction so hydrogen seperates from oxygen?
