Answer:
[tex][/tex] The balanced chemical equation for the production of NH3 from nitrogen gas (N2) is:
N2 + 3H2 -> 2NH3
From the equation, for every 1 mole of N2 that reacts, 2 moles of NH3 are produced. Therefore, to produce 5 moles of NH3, you would need = 5/2 = 2.5 moles of N2.
So, 2.5 moles of nitrogen gas are needed to produce 5 moles of NH3.
