Consider 100 moles of a gas stream containing 15 mol% cs2, 18 mol% o2, and 67 mol% n2. the gas is fed to a continuous absorption tower, where it contacts liquid benzene, which absorbs cs2, but not o2 or n2. benzene is fed to a column in a 2: 1 mole ratio to the feed gas. some of the benzene entering as liquid evaporates and leaves the top of the tower as vapor. the gas leaving the absorber contains 2 mol% cs2 and 2 mol% benzene. how many independent material balances can you write?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
