25 points , hi! please look at the attachment for the question, I'm having a hard time because all I have to do is solve through
MAXImum [283]

Answer:

To answer the question, we correctly fill the attached screenshot as follows;

  • 3H₂ + N₂ → 2NH₃
  • The molar mass of H₂ = 2 g/mol

100.0 g \ H_2 \times \dfrac{1 \ mol \ H_2}{2 \ g \ H_2} \times \dfrac{2 \ mol \ NH_3}{3 \ mol \ H_2} = 33.\bar 3 \ mol \ NH_3

The molar mass of N₂ = 28 g/mol

100.0 g \ N_2 \times \dfrac{1 \ mol \ N_2}{28 \ g \ N_2} \times \dfrac{2 \ mol \ NH_3}{1 \ mol \ N_2} \approx 7.143 \ mol \ NH_3

A. Therefore, the excess reactant is hydrogen gas H₂ because it makes the most amount of ammonia, NH₃ (33.\bar 3 moles of NH₃)

B. The limiting reactant in nitrogen, N₂, because it is the reactant that makes the least amount of the ammonia, NH₃ (approximately 7.143 mol NH₃)

C. The theoretical yield of ammonia, is the maximum amount of ammonium that can be produced from the reaction between the 100 g of hydrogen gas, H₂, and 100 g of nitrogen gas, N₂ which is given by the amount of ammonia produced by the limiting reactant which is approximately 7.143 mole of NH₃
