A reaction involves 2 moles of H_2 and 2 moles of O_2 reacting to form H_2O according to the balanced equation 2 H_2 + O_2 rightarrow 2 H_2O.
Which of the following is true at the completion of the reaction?
- H_2 is the limiting reagent, and 1 mole of O_2 remains.
- O_2 is the limiting reagent, and all O_2 is consumed.
- 4 moles of H_2O are produced.
- Neither reactant is limiting as they are present in equal molar amounts.
