▼

Final Answer:
15 liters

──────────────────────────────────────

Explanation:
We are given the balanced chemical equation:
N₂ + 3H₂ → 2NH₃

This tells us that 1 volume of nitrogen gas (N₂) reacts with 3 volumes of hydrogen gas (H₂) to make ammonia.

The problem says we have 5 liters of nitrogen.
Since the ratio of N₂ to H₂ is 1 : 3, we multiply the volume of N₂ by 3 to get the needed volume of H₂:

5 L N₂ × 3 = 15 L H₂

So, 15 liters of hydrogen are necessary.
