1. Balanced Chemical Equation:

The balanced chemical equation for the reaction of nitrogen and hydrogen to form ammonia is:

N₂ + 3H₂ → 2NH₃

2. Mole Ratio:

The balanced equation tells us that 3 moles of hydrogen (H₂) react to produce 2 moles of ammonia (NH₃).

3. Calculation:

* Start with the given moles of hydrogen: 7.5 moles H₂

* Use the mole ratio from the balanced equation: (2 moles NH₃ / 3 moles H₂)

* Multiply to find moles of ammonia: 7.5 moles H₂ × (2 moles NH₃ / 3 moles H₂) = 5 moles NH₃

Answer: You can make 5 moles of ammonia if 7.5 moles of hydrogen react with enough nitrogen.
