What elements do all hydrocarbons contain?

Answer 1

Hydrocarbon fuels contain a mixture of molecules classified as "hydrocarbons" along with various other non-hydrocarbon components which may or may not have fuel value. A hydrocarbon is a molecule that has a carbon backbone with hydrogen attached along the backbone. Simplest hydrocarbon is Methane (CH4). Hydrocarbons are generally associated with fossil fuels, but need not come just from fossil fuels. For example: Methane is a common byproduct of decaying organic matter. Global warming alarmists have noted the large amount of methane emitted from belching and flatulent cattle.

Hydrocarbon fuels usually contain other organic and inorganic compounds such as alcohols, keytones, ethers, and esters. They may contain partially oxygenated and nitrated compounds. Some contain hydrogen sulfide and other sulfur compounds. Since many (if not most) hydrocarbon fuels are fossil fuels and fossils are found in the ground - other common components of the ground (aka "dirt") are also mixed in with the hydrocarbon fuels. These inorganic compounds usually manifest themselves as ash after the hydrocarbon fuel is burned. Some of the common inorganic components are silica compounds and metals, although other nonmetallic components like Boron may also be present.
