N2 + O2 + 2 NO AH = 43.2 kcal and
Based on the reaction shown, which statement is true?
43.2 kcal are consumed when 1.00 mole of O2 reacts.
cing
43.2 kcal are produced when 1.00 mole of NO is produced.
43.2 kcal are consumed when 1.00 g of NO is produced.
43.2 kcal are consumed when 1.00 g of N2 reacts.
O
43.2 kcal are consumed when 1.00 g of O2 reacts.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

answer; i believe that the correct answer is (a) potassium(k)

it's filtration, but this is an assumption so my apologies if i got this
