Consider the combustion of propane: C3H3 + 502 - 3C02 + 4H20 Which of the following unit factors below is correct? (Select all that may apply) There are 10 oxygen atoms reacting for every six oxygen atomş produced in CO2.
There are 10 oxygen atoms reacting for every four water molecules produced.
There are 5 oxygen molecules reacting for every six oxygen atoms produced in CO2.
There are 5 oxygen atoms reacting for every 3 CO2 molecules produced.​

n2(g) + 3h2-> 2nh3(g)   this is the balanced equation

note the mole ratio between n2, h2 and nh3.   it is 1 : 3 : 2   this will be important.

moles n2 present = 28.0 g n2 x 1 mole n2/28 g = 1 mole n2 present

moles h2 present = 25.0 g h2 x 1 mole h2/2 g = 12.5 moles h2 present

based on mole ratio, n2 is limiting in this situation because there is more than enough h2 but not enough n2.

moles nh3 that can be produced = 1 mole n2 x 2 moles nh3/mole n2 = 2 moles nh3 can be produced

grams of nh3 that can be produced = 2 moles nh3 x 17 g/mole = 34 grams of nh3 can be produced

note:   the key to this problem is recognizing that n2 is limiting, and therefore limits how much nh3 can be produced.

a is the answer to this question
