Final answer:
The balanced chemical equation for the complete combustion of isooctane (C8H18) is: C8H18(g) + 25O2(g) -> 8CO2(g) + 9H2O(g). During complete combustion, a hydrocarbon reacts with oxygen to produce carbon dioxide and water.
Step-by-step explanation:
The balanced chemical equation for the complete combustion of isooctane (C8H18) is:
C8H18(g) + 25O2(g) → 8CO2(g) + 9H2O(g)
During complete combustion, a hydrocarbon reacts with oxygen to produce carbon dioxide and water. The number of carbon and hydrogen atoms remains the same, but they combine with oxygen to form carbon dioxide and water, respectively.
