1. Balanced Chemical Equation

The balanced chemical equation for the synthesis of ammonia (NH₃) from hydrogen (H₂) and nitrogen (N₂) is:

N₂ + 3H₂ → 2NH₃

2. Mole Ratio

From the balanced equation, we see that 3 moles of H₂ react to produce 2 moles of NH₃. This gives us a mole ratio of 3:2 (H₂ : NH₃).

3. Calculation

* Start with the given moles of H₂: 1.5 moles H₂

* Use the mole ratio to find moles of NH₃: (1.5 moles H₂) * (2 moles NH₃ / 3 moles H₂) = 1 mole NH₃

Answer: 1.5 moles of H₂ will produce 1 mole of NH₃.
