The following balanced equation shows the decomposition of ammonia (NH3) into nitrogen (N2) and hydrogen (H2). 2NH3 → N2 3H2 A quantity of NH3 decomposes to produce 0. 0351 mol N2. How many moles of H2 are produced? 0. 0351 mol H2 0. 0117 mol H2 0. 105 mol H2.

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

The answer should be vaporization

The mole ratio of hydrogen to ammonia is 3: 2.
