1. a. The coefficients are 1 for N₂, 3 for H₂, and 2 for NH₃.
b. The particle model shows one N₂ molecule reacting with three H₂ molecules to produce two NH₃ molecules.

2. a. For 1 mole of N₂ and 3 moles of H₂, 2 moles of NH₃ are produced.
b. For 3 moles of N₂ and 9 moles of H₂, 6 moles of NH₃ are produced.
c. For 10 moles of N₂ and 30 moles of H₂, 20 moles of NH₃ are produced.
d. For 5 moles of N₂ and 15 moles of H₂, 10 moles of NH₃ are produced.
e. For 0.5 moles of N₂ and 1.5 moles of H₂, 1 mole of NH₃ is produced.
f. For 0.1 moles of N₂ and 0.3 moles of H₂, 0.2 moles of NH₃ are produced.

3. a. The ratio of moles of reactants consumed to moles of product produced is always 1:3:2 (N₂:H₂:NH₃).
b. If 50 moles of N₂ react, 100 moles of NH₃ are produced.
c. If 50 moles of H₂ react, approximately 33.33 moles of NH₃ are produced.
d. If 50 moles of NH₃ are produced, 25 moles of N₂ and 75 moles of H₂ are consumed.
