How many molecules of O₂ will be required to react completely with 0.600 moles of H₂ in order to form water?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction between O₂ and H₂ to form water is: O₂ + 2 H₂ → 2 H2O + ₂ From the equation, we can see that 1 mole of O₂ will react with 2 moles of H₂ to form 1 mole of ₂. Therefore, to react completely with 0.600 moles of H₂, we need: 0.600 moles H₂ × 1 mole O₂ / 2 moles H₂ = 0.300 moles O₂ Using the Avogadro's number, we can convert moles to molecules: 0.300 moles O₂ × 6.022 × 10^23 molecules/mole = 1.81 × 10^23 molecules O₂ Therefore, the answer is C: 1.81 11ea7f51_1e8e_6b79_9ecd_a375642d3dea_TB4036_11 10²³.
