We are required to reduce the DMF content of the raw feed from 55 mol%(balance is nitrogen). A separator is designed to remove exactly two-thirds of theDimethyl Formamide (DMF) fed to it. The extract will contain DMF in a pure form.(a) (10 points) Draw a PFD for the above and perform a degree of freedom analysis.(b) (8 points) Solve for the exit stream composition. Did you choose a basis

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
