Per NCERT, the balanced equation for the COMBUSTION OF PROPANE (C₃H₈) with oxygen is which?
AC₃H₈ + 3O₂ → 3CO₂ + 4H₂O
BC₃H₈ + 5O₂ → 3CO₂ + 4H₂O
CC₃H₈ + O₂ → CO₂ + H₂O
DC₃H₈ + 7O₂ → 3CO₂ + 4H₂O
Answer & Solution
Correct answer: B. C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Per NCERT §Balancing (Steps 1-5), propane: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O. Total O on right = 6 + 4 = 10 → 5 O₂ on left.
