Thirty moles of hydrogen and 14 moles of oxygen should react to produce 252 grams of water and 2 grams of hydrogen.

Question

Quizplus · Accepted Answer

The reaction between hydrogen and oxygen to form water is described by the balanced chemical equation: 2H₂ + O₂ → 2H₂O. This means 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. Given the molar masses (H₂ = 2.02 g/mol, O₂ = 32.00 g/mol, H₂O = 18.02 g/mol), 30 moles of hydrogen would ideally react completely with 15 moles of oxygen to produce 30 moles of water, which would weigh 540.6 grams (30 moles * 18.02 g/mol). The provided numbers do not match the expected stoichiometry and product mass.
