Ethanol (ch 3 ch 2 oh) is dehydrogenated in the presence of air over a catalyst, and the following reactions take place: ch3 ch2 oh → ch3 cho + h2 2ch3 ch2 oh + 3o2 → 4co2 + 6h2 2ch3 ch2 oh + 2h2 → 4ch4 + o2 separation of the product, ch3 cho (acetaldehyde), as a liquid leaves an output gas with the following orsat analysis: co2 0.7%, o2 2.1%, co2.3%, h2 7.1%, ch4 2.6%, and n2 85.2%. how many kilograms of acetaldehyde are produced per kilogram of ethanol fedinto the process?

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.
