The Haber Process hydrogen gas and nitrogen gas
combine to form ammonia gas
QuickTime™ and aTIFF (Uncompressed) decompressorare needed to see this picture.
Skeleton equation:
N2 (g) + H2 (g) -> NH3 (g)Balanced equation:
N2 (g) + 3H2 (g) -> 2NH3 (g)

ON RAMP: change grams of what you have into moles
BRIDGE: change moles of one material into moles of another
OFF RAMP: change moles of what you want back into grams

N2 (g) + 3H2 (g) -> 2NH3 (g) 10.0 g ?
ON RAMP: change grams of what you have into moles
OFF RAMP: change moles of what you want back into grams
BRIDGE: change moles of one material into moles of another
= 2.16 g H2 needed to react with 10.0 g N2
10.0 g N2 x 1 mole N2
28.0 g N2
x 3 mol. H2
1 mol. N2
x 2.02 g H2
1 mol. H2
How many grams of hydrogen would we need to convert 10.0 g of nitrogen into ammonia?

How many grams of ammonia can be made from 10.0 g nitrogen?
N2 (g) + 3H2 (g) -> 2NH3 (g) 10.0 g ?
ON RAMP: change grams of what you have into moles
OFF RAMP: change moles of what you want back into grams
BRIDGE: change moles of one material into moles of another
= 12.1 g NH3 can be made with 10.0 g N2
10.0 g N2 x 1 mole N2
28.0 g N2
x 2 mol. NH3
1 mol. N2
x 17.0 g NH3
1 mol. NH3

Check your answer using Conservation of Mass.
N2 (g) + 3H2 (g) -> 2NH3 (g)
10.0 g N2 + 2.16 g H2 =12.1 g NH3 ?
12.16 g =12.1 g ?
yes, to within + 0.1 g
