The moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.

The balanced chemical equation for the decomposition of Ammonia has been:

[tex]\rm 2\;NH_3\;\rightarrow\;N_2\;+\;3\;H_2[/tex]

From the balanced chemical equation, decomposition of 2 moles of ammonia produces, 3 moles of hydrogen and 1 mole, nitrogen.

The moles of hydrogen produced along with 0.0351 mol nitrogen has been:

[tex]\rm 1\;mol\;N_2=3\;mol\;H_2\\ 0.0351\;mol\;N_2=0.0351\;\times\;3\;mol\;H_2\\ 0.0351\;mol\;N_2=0.105\;mol\;H_2[/tex]

Thus, the moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
