Fuel cells are a particular type of electrochemical cell that requires a constant source of reactants during operation. for example, a hydrogen fuel cell operates using hydrogen and oxygen as fuels. consider the operation of a hydrogen fuel cell under basic conditions, for which oh- ions are much more likely than h3o+ ions.

what species is/are formed at the cathode of the alkaline fuel cell? a)h+ b)oh- c)h20 d)o2 e)h2 f)e-

0.2348 grams of pbcl2 used to form 44.0 ml of solution.

Explain that newton first law,second law and third law of motion?

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.
