For 2 H₂ + O₂ → 2 H₂O, 4.0 g H₂ and 32.0 g O₂ are mixed.
Which is the limiting reagent?
- A
O₂
- Bcheck_circle
Both are stoichiometric — neither is limiting.
- C
Cannot determine.
- D
H₂
Explanation
Need 2 mol H₂ per 1 mol O₂. We have exactly 2.0 mol H₂ and 1.0 mol O₂ — perfect stoichiometric ratio, no limiting reagent.
