Wastewater at 600 gpm, containing 10 ppm (by weight) of benzene, is to be stripped with air in a packed column, operating at 25∘c and 2 atm, to produce water containing 0.005 ppm of benzene. the packing is 2-inch polypropylene flexirings. the vapor pressure of benzene at 25∘c is 95.2 torr. the solubility of benzene in water at 25∘c is 0.180 g∕100g. an expert∘in voc stripping with air suggests the use of 1,000 scfm of air (60 f, 1 atm). at these conditions, for benzene,

The picture represents the process that produces most of the energy used by living organisms on earth. which process is represented in the picture? a) the magnetic attraction between two hydrogen nuclei. b) the fusion of hydrogen nuclei to produce a helium nucleus in the core of the sun. c) the fission of hydrogen nuclei to produce a helium nucleus in the core of the sun. d) the chemical reaction between hydrogen nuclei to produce a helium nucleus in earth's atmosphere.

Water undergoes a large change in density at 0 ∘ c as it freezes to form ice. calculate the percent change in density that occurs when liquid water freezes to ice at 0 ∘ c given that
