Question
Please explain the atomic balances!
Octane (C8H18) is burned in a model airplane engine using a stoichiometric feed based on full combustion. A majority (70.0 mol %) of the octane is converted to carbon dioxide, and another 25.0 mol % is converted to carbon monoxide. Answer the following questions for this combustion reaction. Balance the reactions: C8H18 + 0₂ C8H18 + 0₂ Given a basis of 1.50 mol octane: CO₂ + H₂O CO + H₂O a. How many moles of O₂ are supplied? How many moles of air? b. Use an atomic balance on hydrogen to determine the moles of water produced. c. How much CO2 is produced? How much CO is produced? d. Use an atomic balance on oxygen to determine the residual moles of O2.
