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?

is has three carbons, so the answer is propylamine.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
