The balanced chemical equation for the formation of ammonia from nitrogen and hydrogen is:

\[ \text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3 \]

From this equation, we can derive the correct ratios:

  1. For every mole of nitrogen gas (N₂), the reaction produces 2 moles of ammonia (NH₃).
  2. For every 3 moles of hydrogen gas (H₂), the reaction produces 2 moles of ammonia (NH₃).
  3. For every 2 moles of nitrogen gas (N₂), the reaction requires 6 moles of hydrogen gas (H₂) to produce 4 moles of ammonia (NH₃).

Now, evaluating the options:

  1. "For every mole of nitrogen gas, the reaction produces 1 mole of ammonia." - Incorrect
  2. "For every 2 moles of nitrogen gas, the reaction requires 3 moles of hydrogen gas." - Incorrect
  3. "For every mole of hydrogen gas, the reaction produces 2 moles of ammonia." - Incorrect
  4. "For every 3 moles of hydrogen gas, the reaction produces 2 moles of ammonia." - Correct

Thus, the correct statement is: For every 3 moles of hydrogen gas, the reaction produces 2 moles of ammonia.
