The two-bed carbon adsorption system will handle 3.78 m3 s-1 (8000 acfm) of air containing 700 ppm of hexane. Pilot plant studies indicate that the carbon can absorb 8 lbm hexane per 100 lbm carbon under the conditions at which the plant will be operating. The operating conditions will be 32.2 C (90 F), 760 mm Hg (1 atm) and a removal efficiency of 99%. Hexane (C6H14) has a molecular weight of 86.18 g/g-mole. The airflow rate is 3.78 m3 s-1 (8000 acfm), air temperature is 32.2 C (90 F) and pressure is 760 mm Hg (1 atm). Find the mass (kg) of carbon needed.

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
