The resulting flue gas in a combustion has the following compositions in mole fraction: 0.072 CO2, 0.018 CO, 0.04 O2, and the rest is N2. Which of the following balances in incorrect?

a. Oxygen atom from air = Oxygen atom in flue gas

b. O2 in = O2 remaining + O2 consumed

c. O2 in air = O2 remaining + O2 from CO2 + O2 from H2O
