The zombie apocalypse is here. you have holed up in a biochemistry lab and have only the chemical shelf for food. on the shelf you see: various monosaccharides, and various sugar alcohols (where the carbonyl of the sugar has been converted to an alcohol). would sugars or sugar alcohols give you more energy per carbon? why? (assume all of these will be transported to your cells equally well.)

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
