Petrol is a hydrocarbon. Its molecular chain contains the water molecule. The heat produced during the burning of petrol as fuel in an internal combustion engine, frees the dihydrogen oxide molecule (water) from the chain. At this point it is held as a gas within the other burnt oxides. The gases are then ported to the exhaust system where the temperature falls and the gas condenses, forming water!

The combustion of petrol (hydrocarbons) involves a chemical reaction with oxygen to produce carbon dioxide, water, and heat. The general equation is: Petrol (hydrocarbon) + Oxygen → Carbon dioxide + Water + Heat

∙ 15y agoBurning of any hydrocarbon fuel in the open air, as opposed to combusting it in an engine or a burner like a camp stove, creates a more limited range of pollutants.
The primary product in either case is carbon dioxide (about 3 kg for every liter burned). The open burning evaporates a portion of the unburned liquid an releases it as hydrocarbon vapour. A portion of the vapour is partially burned and cracked by the flames' heat to produce carbon particulate (soot) and smaller organic compounds than were in the original fluid.
Almost no NOx will be produced as the heat is not high enough.
If the burning is taking place in water, some of the liquid will become heavier as the light ends are evaporated off by the fire's heat and may be left as aresidula when the fire dies down

2C8H18 + 25O2 --> 16CO2 + 18H2O.
That one's a beast to balance. In combustion reactions, do the carbons first. Do the oxygens last. The hydrogens will take care of themselves.

Is burned ethanol a physical or chemical change?
The burning of ethanol is a chemical change because it involves a chemical reaction that changes the composition of the ethanol molecules into new substances such as carbon dioxide and water vapor.
What do you call the energy which is stored in chemical fuels such as petrol?
The energy stored in chemical fuels such as petrol is called chemical potential energy. This energy is released when the fuel undergoes a chemical reaction, such as combustion, which can be harnessed to do work.
How is starting a car a chemical reaction?
Starting a car involves a chemical reaction between the fuel (gasoline) and oxygen in the air. The spark plug ignites the fuel-air mixture in the engine cylinder, leading to a combustion reaction that releases energy in the form of heat, which powers the engine. This chemical reaction generates the energy needed to start the car and keep it running.
Is burning coal a chemical or physical reaction?
Burning coal is a chemical reaction because it involves a chemical change in the coal's composition, transforming it into new substances like carbon dioxide and ash.
Is the burning of gasoline a physical change or a chemical change?
The burning of gasoline is a chemical change because it involves a reaction with oxygen from the air to produce carbon dioxide, water vapor, and energy. This process cannot be easily reversed to recover the original gasoline molecules.
What chemical reaction does petrol use?
Combustion, burning.
Is petrol burning a chemical reaction?
Yes, it is. The petrol turns into a gas.
Is burning petrol a reaction?
Yes, it is. The petrol turns into a gas.
Is petrol in a car a chemical reaction?
Yes, using petrol (gasoline) in a car to produce movement is a chemical reaction.
Burning wood a physical or chemical?
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
What is the chemical reaction of burning a paper?
Burning is an oxydation reaction.
Does burning petrol release energy?
Yes, burning petrol releases energy through a chemical reaction known as combustion. When petrol (a hydrocarbon compound) reacts with oxygen in the air, it produces heat, light, and various byproducts such as carbon dioxide and water vapor, which results in the release of energy.
What evidence of chemical reaction would be seen when burning a match?
Burning is a chemical reaction (oxidation).
Is burning petrol a chemical reation?
Yes. burning petrol chemically creates a whole new set of chemicals. depending on the heat and exact composition of the petrol.
Is yellow flame a chemical reaction?
Yes, a yellow flame is a result of a chemical reaction. When a flame appears yellow, it is often due to the presence of certain chemicals in the fuel or the combustion process that emit light in the yellow part of the electromagnetic spectrum. This color can occur in various types of combustion reactions, such as those involving hydrocarbons.
Is burning of fuel in a cutting torch a chemical reaction?
Yes, burning of fuel is always a chemical reaction.
Why is paper burning a chemical reaction?
Burning is a sign of a chemical change
