A student performed simple distillation on a 40:60mixture of Methanol and water (% mol).
a. At what temperature will the mixture boil?
b. What is the composition of the liquid collected from simple distillation?

2. Another student performed a fractional distillation on the same mixture of 40:60 (%
mol) Methanol/water mixture and found the liquid collected to contain 4% mol of
water.
a. At what temperature did the mixture containing 4% mol of water boil?
b. How many theoretical plates did the fractionating column used in this experiment
have?
c. What would be the minimum number of theoretical plates required to achieve
complete separation of the 40:60 (% mol) methanol-water mixture?

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
