Answer:
66.9 L = NH3
Explanation:
Nitrogen gas = N2= 13.5 L
Hydrogen gas = H2 = 17.8 L
Nitrogen gas react with hydrogen gas to produce ammonia at standard temperature and pressure (STP).
N2 + H2 → NH3
Balance equation:
N2 + 3H2 → 2NH3
13.5 + 3 (17.8) = ?
13.5 + 53.4 = 2NH3
66.9 L = 2NH3
67 L Ammonia will be produced.
