Final answer:
To determine the moles of O₂ required to react with 5.7 moles of C₆H₁₄, refer to the balanced chemical equation and use the mole ratio between C₆H₁₄ and O₂.
Step-by-step explanation:
To determine how many moles of O₂ are required to react completely with 5.7 moles C₆H₁₄, we need to refer to the balanced chemical equation.
The balanced equation is:
C₆H₁₄ + (19/2)O₂ → 6CO₂ + 7H₂O
From the equation, we can see that 1 mole of C₆H₁₄ reacts with (19/2) moles of O₂. Therefore, to calculate the moles of O₂ required, we can use the ratio of moles between C₆H₁₄ and O₂:
(5.7 moles C₆H₁₄) * ((19/2) moles O₂ / 1 mole C₆H₁₄) = 53.65 moles O₂
Therefore, the correct answer is d) 53.65 moles O₂.
