Venus is sometimes thought of as earth's sister planet. in some ways the two planets are very similar. venus is only slightly smaller than earth, has a similar density and chemical composition. yet venus does not support life like earth. what is one important reason why venus cannot support life as we know it?
question 5 options:
venus has no atmosphere.
venus' surface temperature is about 480oc.
the water on venus' surface is too hot to support life.
venus' dense clouds keep the planet's temperature very low.

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.
