What makes fuel in a fuel tank ( ex: carbon, hydrogen,etc.)?

Question

HELP!!!!!!!!!!

Answer 1

The fuel is a mixture of hydrocarbons, usually with 7 to 10 carbon units. The "octane" is actually 2,2-dimethyl, 3-methylpentane. Gasoline is, like octane, comprised of branced methyl groups on a straight chain. If there are no branches, you get kerosine instead. The fuel has additives to help get the ignition process rolling along in the engine. In the good old days, the main additive was tetraethyl-lead, which supplied tetraethyl in a special form for the ignition. So people would ask for leaded or unleaded gas. Lead was phased out in favor of non-leaded additives, such as MTBE, so now all gas is unleaded.

Answer 2

Not quite sure I know what you're looking for, but here goes:
Fuels (as we know them) are hydrocarbons, which means they are primarily composed of hydrogen and carbon. Since all living creatures and plants are composed of the same, it makes sense that fossil fuels are as well! In addition, alcohols can be used as fuels- the only difference is there is an O-H bond incorporated into the system.

Answer 3

Well, I am a chemist. Not to sure what you meen by this. But, fuel is made up of hydrogen and carbon. This is also know as "Octane". The "Oct" is what organic chemists know about the carbon chain. "Oct" means 8, as in 8 carbons in one molecule. The "ane" part of Octane meens that its all single bonds. Octene would be double bonded and Octyne would be triple bonded, thats a far as it goes. Back on track, Octane is what your vehicle burns in the engine. The fuel in the tank is Octane. Hope this helps.
