In ethanol production by fermentation of corn, hydrolyzed ground corn in a water suspension containing 50% corn by weight is mixed with sufficient enzyme to produce ethanol by the approximate reaction 3.6 c& h12o6 2c2h5oh+ 2co2 when the solution reaches 12 wt% ethanol, the yeast dies and the reaction stops. how many bushels of corn are required to produce 500 tons of pure ethanol (a) per day? (1 bushel = 25 kg, 1 ton-907 kg as opposed to 1 tonne 1000 kg) the process requires 72 hours to go to completion. what size batch-reactor (b) tank or tanks are required for this process? assume density of starch 1000 kg/m3.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
