A gaseous mixture of and contains 35.8 nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 585 ?
How is "soap" chemically different from "detergent"? What chemical features and properties of detergents make them better than soap for hard water applications?
Perform a similar analysis of a stripping column. In this case, 100 lbmol/h of water with a concentration of 0.0045 lbmol SO2/ft3 is stripped with air to a concentration of 0.0005 lbmol SO2/ft3. The air flow rate is 1.5 times the minimum.
