air is bubbled through a drum of liquid hexane at a rate of 0.200 kmol / min. the gas stream leaving the drum contains 10.0 mole's hexane vapor. air may be considered insoluble in liquid hexane. use an integral balance to estirmate the time reguired to vaporize in min to vaporize 10.0 m of the liquid. if the total moles of the products 0.222 kmol / min and the specific gravity of liquid hexane is 0.659 and the accumulation term equals -76.45 kmol ch4

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt

Which process describes vaporization that takes place below the surface of a liquid? condensation melting boiling evaporation
