Answer :
Final answer:
The balanced chemical formula for the combustion of 1-propanol is: C₃H₈O + 6O₂ → 3CO₂ + 4H₂O. The molar mass calculations show that there are fewer moles of oxygen than needed based on the stoichiometry, hence oxygen is the limiting reactant.
Explanation:
The balanced chemical formula for the combustion of 1-propanol is: C₃H₈O + 6O₂ → 3CO₂ + 4H₂O. This indicates 1 mole of 1-propanol reacts with 6 moles of oxygen to yield 3 moles of carbon dioxide and 4 moles of water. Using the stoichiometry of the reaction, we can determine the limiting reactant. The molar mass of 1‑propanol is about 60.1 g/mol and that of oxygen is 32 g/mol. Thus, we have 6.50/60.1 ≈ 0.108 moles of 1-propanol and 37.1/32 ≈ 1.16 moles of oxygen. Because we need 6 moles of oxygen for every mole of 1-propanol, and we have less than that (1.16 / 0.108 ≈ 10.7), oxygen is the limiting reactant in this reaction.
