The burning of gasoline to power internal combustion engines produces water vapor, and carbon dioxide gas that is thought to contribute to the "Greenhouse Effect" in the earth's atmosphere. Write the balanced chemical equation for burning gasoline (assume octane reacting with oxygen).

the equation of the octane and balanced combustion is as follows:

2C8H18 + 25O2 = 16CO2 + 18H2O

Explanation:

Octane combustion is a chemical chain reaction, producing heat.

The spark-ignited combustion engine transforms the thermal energy from the combustion of gasoline plus air into motive energy. The combustion of gasoline is preceded by the formation of gasoline and air in the carburettor, this mixture enters the cylinder through the supply system, then is compressed by the upward stroke of the piston and then inflamed by the spark. Due to combustion, the volume of the mixture increases rapidly, creating a strong pressure that moves the piston.

the balanced equation to the combustion of gasoline is C8H18 + 12.5 O2 → 8 CO2 + 9 H2O (1)
