Final answer:
The chemical reaction in question is between nitrogen gas (N₂) and hydrogen gas (H₂) to produce ammonia (NH₃), and it follows the balanced equation: 3H₂ + N₂ → 2NH₃.
Step-by-step explanation:
The student's question relates to the chemical reaction where nitrogen gas (N₂) reacts with hydrogen gas (H₂) to form ammonia (NH₃). This reaction is described by the balanced chemical equation:
3H₂(g) + N₂(g) → 2NH₃(g)
In the example given, they mention that two molecules of nitrogen gas would react with six molecules of hydrogen gas. Using the balanced equation, we can infer that one molecule of nitrogen reacts with three molecules of hydrogen to form two molecules of ammonia. Therefore, when working with moles, one mole of nitrogen would react with three moles of hydrogen to yield two moles of ammonia. In their scenario with two (2) molecules of nitrogen, it would react with six (6) molecules of hydrogen, which is consistent with the balanced equation if you consider that each 'molecule' term is effectively a placeholder for moles in this context.
