what might be the reason that this is happening:
During a simple distillation i have 14ml or 50/50 hexane;toluene mixture in a 25mL round-bottom flask. However, by the time i collected 8ml of distillate there were no liquid left in the flask.
Some loss is due to liquid adhering to the walls of the distillation flask, condenser, etc. A second place may be that the vapor exited the distillatioln set up without condensing.
a mixture of 2.0 mol of co and 2.0 mol of h2o was allowed to come to equlibrium in a 1l flask at high temperature. if kc=4.0 what is the molar concentration of h2 in the equlibrum mixture?
Co(g)+ H20 (g) ---> Co2 (g) + H2
