(1) The number of moles of nitrogen trihydride produced is 3.63 moles.
(2) The molar ratio not represented is 2 moles of N₂ = 3 moles of NH₃.
Chemical reaction of Nitrogen and hydrogen
The balanced chemical reaction of Nitrogen and hydrogen is given in the equation below;
N₂ + 3H₂ → 2NH₃
From equation above;
3 moles of H₂ --------------------> 2 moles of NH₃
5.45 moles of H₂ ----------------> ? moles of NH₃
= (5.45 x 2) / 3
= 3.63 moles of NH₃
Molar ratio not represented in the above balanced equation
From the equation above, we have the following molar ratios
- 2 moles of NH₃ = 3 moles H₂
- 1 mole of N₂ = 2 moles of NH₃
- 3 moles H₂ = 1 mole of N₂
Thus, the only molar ratio not represented in the balanced chemical equation of Nitrogen and hydrogen gas is 2 moles of N₂ = 3 moles of NH₃.
