N2 (g) + 3H2 (g) -> 2NH3 (g)
assume 4 molecules of nitrogen and 9 molecules of hydrogen are present.
after complete reaction, how many molecules of ammonia are produced.
do i go from N to NH3 or H to NH3?
ammonia: 6 produced
H2: 0 remain since the 3H2 where combined
Moles of N2 remain: 1 since 4-3=1
