A gas‑filled weather balloon has a volume of 54.0 L at ground level, where the pressure is 751 mmHg and the temperature is 22.3 ∘C. After being released, the balloon rises to an altitude where the temperature is −2.54 ∘C and the pressure is 0.0715 atm. What is the weather balloon's volume at the higher altitude?

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

How many miles of water are produced if 5.43 mol pbo2 are consumed

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.
