Why does fuel produce carbon dioxide?

Answer 1

Yes. Fuel oil consists of alkane hydrocarbons. For example, Cetane consists of a chain of 16 carbon atoms. Diesel, one type of fuel oil, is a mixture of carbon molecules that contain between 8 and 21 carbon atoms per molecule.

When a hydrocarbon is burned, carbon dioxide and water are released. For example, burning one molecule of Methane (CH4) with two molecules of Oxygen (O2) produces one molecule of Carbon Dioxide (CO2) and two molecules of Water (H2O).

CH4 + 2 O2 -> CO2 + 2 H2O

The combustion equations for more complex hydrocarbons are similar, just more complicated!

So, when fuel oil is burned, Carbon Dioxide and Water are released. Because of the heat of combustion, the water is present as gas (Superheated Steam or Water Vapour, depending on the temperature).

Answer 2

When fuel (such as gasoline or coal) is burned for energy, the carbon atoms in the fuel combine with oxygen in the air to produce carbon dioxide (CO2) as a byproduct. This process is known as combustion. The carbon in the fuel is oxidized to form CO2, which is released into the atmosphere.

Answer 3

Because when petrol ,a fossil fuel, is burned carbon monoxide is formed as well as carbon dioxide. So because cars use petrol carbon monoxide is formed in cars engines. Carbon monoxide is also toxic.

Answer 4

Your car doesn't smell like carbon monoxide because carbon monoxide is invisible and odorless. I can't suggest what caused that smell because I have no way of knowing what it smells like.

An exhaust leak will cause your car to smell like exhaust ( and has carbon monoxide in it) and is hazardous to you and your passengers.

Answer 5

This is because cars burn off Carbon Dioxide. They do have Eco friendly cars now but are more expensive. After they have used the Carbon Dioxide to run, they let it out of the back.

Hope this helped !! xx

Answer 6

Carbon monoxide is a result of the incomplete combustion of mineral fuels (petrol or gas) with oxygen. More complete combustion gives carbon dioxide as a waste product. Normal cars will produce both, often along with other compounds such as sulphur dioxide.

Answer 7

car exhaust releases carbon dioxide because the gas has burned and it brings out carbon dioxide

Answer 8

Dude, this is basic knowledge. When cars burn fuel nitrogen is released which fuses with sun rays from the sun and forms carbon monoxide.

Answer 9

It is a natural product of the combustion of gasoline.

Answer 10

Because the combustion of organic compounds in the presence of oxygen produces carbon dioxide and water.
