Question

When 7g nitrogen reacts with 3g hydrogen to form ammonia .Find out amount of Ammonia and volume at STP

Answer 1

Answer:

N2 + 3H2———→2NH3

So 28 gm of N2 will react with 6 gm of H2, to form (2 moles) 34 gm of Ammonia.

So 7gm of N2 will react with=6 x7/28=1.5 gm. So the amount of Ammonia gas forward will be =7+1.5=8.5 gm.

7 gm of Nitrogen will react with only 1.5 gm of Hydrogen and will give 8.5 gm (0.5 mole) Ammonia. The rest 1.5 gm Hydrogen will be left unreacted.
