Answer:
True
Step-by-step explanation:
Liquid hexane burns in oxygen gas to form carbon dioxide gas and water vapor. TRUE.
This is the complete combustion reaction of hexane, which proceeds according to the following equation.
C₆H₁₄(l) + 9.5 O₂(g) → 6 CO₂(g) + 7 H₂O(g)
If the combustion were incomplete, instead of carbon dioxide, the product would be carbon monoxide or carbon.
