A 30L digester bioreactor is charged with media and 3.75L of cow dung. The reactor produces 5L of biogas per one liter of cow dung at a pressure of 1 atm and a temperature of 27oC. The biogas leaving the digester is saturated with water. On a dry basis, this gas contains 80 mol% methane and 20 mol% carbon dioxide. The gas is then fed to a furnace with 7 mols of dry air and undergoes complete combustion and complete conversion. Determine the composition of the resulting gas. Assume ideal gases.
Soft drinks are bottled under CO2 pressure of 4.0 atm. The solubility of CO2 at 4.0 atm is 0.71g/100g H2O. What is its solubility after the bottle is opened if the partial pressure of CO2 is 4.0e-4 atm
