Question

What is the volume of the product in the following reaction: O₂ (g) + 2H₂ (g) → 2 H₂O (g) if the reactants are 1 liter of oxygen and 2 liters of hydrogen?

Quizplus · Accepted Answer

The reaction follows the stoichiometry of 1 mole of oxygen reacting with 2 moles of hydrogen to produce 2 moles of water vapor. Given that all gases are under the same conditions, their volumes are directly proportional to the moles. Since 1 liter of oxygen reacts completely with 2 liters of hydrogen, the product volume will be 2 liters of water vapor, according to the stoichiometry of the reaction.
