There are wetlands that exist in South Dakota. I would like you to tell me the type of the wetlands in the state (I am thinking specifically the wetlands in the Lacreek refuge and the wetlands in eastern South Dakota-they are different types). Classify them, provide the value and function of them. Be sure to tell me about the plants, animals, macroinvertebrates, water quality-chemistry, soil types, etc. Why are wetlands important in these areas of South Dakota? What is the keystone species of the wetlands? How is this species important to the wetlands in South Dakota. Is Pollution affecting the wetlands in South Dakota? What is causing this pollution? How could you change that? Is Climate change affecting the wetlands? How/Why? You should have 2 full pages (double spaced of typing, 12 pt font, 1 inch margins, calibri or new time roman font).

A Student in mass transfer operation lab accidently spills 10 litres of gasoline, which quickly spreads over a level surface of area 10 m2 . Estimate the time required for the gasoline to evaporate into the stagnant air above the surface of the liquid. The diffusivity of gasoline in air is 0.65 m2 h -1 . The air temperature is 298 K. Evaporation may be assumed to take place through a film of air of 2 mm thickness. Vapour pressure of gasoline at 298 K is 76 mmHg. The density of gasoline is 720 kg m-3 and the molecular weight of gasoline is 200. The operation takes place at 1 atm pressure

In industry, an ethylene oxide is produced with air. Under operating conditions, much of the ethylene is converted to ethylene oxide, another part is fully oxidized to CO2 and water, and the rest is unreacted. The gases leave the reactor and go to an absorption column where the water will absorb all the ethylene oxide. The exhaust gases from the absorption column have 9.6% CO2, 6.4% C2H4, 3% O2, and 81% N2. % of ethylene entering the reactor is converted to ethylene oxide and what% remains unreacted? What is the ethylene / air ratio?

A unit square of chemical X and two centimeters square of chemical Y is needed to produce product II given a resource constraint of 11. Product III needs only chemical X and requires at least two centimeters square volume of chemical X while product IV requires a unit centimeter square of chemical X and three centimeters square of chemical Y with a constraint of 15. The company makes a profit of ¢3000 for using a unit of X and ¢5000 for a unit of Y.
