Determine the amount of all species (N₂, O₂, CO₂, and H₂O) in the exhaust from the complete combustion of 1 mole propane (C₃H₈). Assume 50% excess air (79% N₂, 21% O₂) is the source of oxygen.
a) N₂: 2 moles, O₂: 5 moles, CO₂: 3 moles, H₂O: 4 moles
b) N₂: 1 mole, O₂: 4 moles, CO₂: 3 moles, H₂O: 4 moles
c) N₂: 2 moles, O₂: 4 moles, CO₂: 3 moles, H₂O: 5 moles
d) N₂: 1 mole, O₂: 5 moles, CO₂: 4 moles, H₂O: 3 moles
