Part D Jupiter's moon Europa is unique. Underneath its crust, which is made of ice, is a layer of liquid water. This liquid layer
likely contains more water than there is on Earth. The liquid layer causes Europa to be extremely tectonically active, with
new crust being formed constantly. How does this level of tectonic activity on Europa likely reduce the number of visible
impact craters?

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.
