What would be the result if we heated a mixture of dichloromethane (bp 39-40 degrees Celsius) and napthalene (C10H8, mp 80-82 degrees Celsius and bp 218 degrees Celsius) to 60 degrees Celsius, collected distillate until no further material distilled and then cooled the flask back to room temperature. (THis type of mixture might also be obtained at the end of an extraction experiment starting with a mixture of benzoic acid, benzocaine, and napthalene.
A chemist decomposes several samples of water into hydrogen and oxygen and weighs the hydrogen and oxygen obtained. The results are: 1) 1.5g H and 12g O 2) 2g H and 16g O 3) 2.5g H and 20g O.
