. Nitrogen and hydrogen react to form ammonia
Nitrogen and hydrogen react to form ammonia.
N2 (g) + 3H2 (g) →2NH3 (g)
If 1000g H2 react with 2000g of N2:
(a) Will any of the two reactants remain unreacted? If yes, which one and what will be its mass?
(b) Calculate the mass of ammonia(NH3) that will be formed?
N2 + 3H2 →2NH3
28g of nitrogen requires hydrogen = 6g
2000g of nitrogen requires hydrogen = 6/28×2000=3000/7g
So mass of hydrogen left unreacted =1000-3000/7=571.4g of H2
(b)28g of nitrogen forms NH3 = 34g
2000g of N2 forms NH3
