Two of the types of ultraviolet light, uvb and uvc, are both components of sunlight. their wavelengths range from 280 to 320 nm for uvb and from 100 to 280 nm for uvc. compare the energy of microwaves, uvb, and uvc. rank from greatest to least energy per photon. to rank items as equivalent, overlap them.

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.
