The reaction of H2 and O2 to form water is given by 2H2 + O2 → 2H2O. If 3 moles of H2 react with 1 mole of O2, find the limiting reagent.
Correct: B
Using the stoichiometry of the reaction, 2 moles of H2 react with 1 mole of O2 to form 2 moles of H2O. Given 3 moles of H2 and 1 mole of O2, the O2 is the limiting reagent.
