What is the balanced equation for the combustion of propane (C3H8) in oxygen?
1
C3H8 + 5O2 → 3CO2 + 4H2O
2
C3H8 + 4O2 → 3CO2 + 5H2O
3
C3H8 + 3.5O2 → 3CO2 + 4H2O
4
C3H8 + 2O2 → CO2 + 2H2O
Answer and Solution
Answer
A. C3H8 + 5O2 → 3CO2 + 4H2O
Solution:
The correct balanced equation is C3H8 + 5O2 → 3CO2 + 4H2O, representing complete combustion of propane. The other options either miscount O2 molecules or do not balance properly.
