The exit gas from an alcohol fermenter consists of an air–co2 mixture containing 10 mol% co2 that is to be absorbed in a 5.0-n solution of triethanolamine, containing 0.04 mol co2 per mol of amine solution. assume that the column operates isothermally at 25∘c, the exit liquid contains 78.4% of the co2 in the feed gas to the absorber, and absorption is carried out in a six-theoretical-plate column. then use the equilibrium data below to calculate (a) exit-gas composition and (b) moles of amine solution required per mole of feed gas.

the answer to your question is b

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
