How much heat, in kj, is produced by the amount of octane needed to drive 573 kilometers in a car that averages 22.8 km/l?

Respuesta :

Combustion of octane

16 CO2(g) + 18 H2O = 2 C3H18(1) + 25 O2(g) (1)

ΔΗO -10, 932 kJ

What is combustion?

Combustion is the process of a substance burning in the presence of oxygen to produce heat and light.

You may have heard that some materials are combustible while others are not. Simply put, combustible compounds are those that go through this process.

Burning is actually referred to as combustion in science. Burning is a phenomenon that we are all familiar with, but did you realise that it is also a chemical reaction? Any fuel reacts chemically with air (an oxidant) during combustion to produce heat energy. Additionally, a flame will appear as a result of the release of heat energy.

Following complete combustion, octane (C,H,g, density = 0.699 g/mL) produces energy as shown by the following reaction:

16 CO2(g) + 18 H2O = 2 C3H18(1) + 25 O2(g) (1)

ΔΗO -10, 932 kJ
