Most do, some don't. Coal contains very little hydrogen, petroleum contains quite a bit.
No, not all fossil fuels contain methane. Fossil fuels primarily consist of carbon and hydrogen, with varying amounts of other elements like sulfur, nitrogen, and oxygen. Methane is mainly found in natural gas, which is a fossil fuel, but not all fossil fuels contain methane.
Coal, petroleum, and natural gas all contain hydrocarbons, which are organic compounds composed of hydrogen and carbon atoms. These hydrocarbons are the main components of fossil fuels, providing energy through combustion.
Oxygen is required for the combustion of fossil fuels. During combustion, the carbon and hydrogen in the fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
Fossil fuels such as coal, oil, and natural gas burn because they contain chemical energy stored from ancient organic matter. When exposed to heat or a spark, the carbon and hydrogen in fossil fuels react with oxygen in the air, releasing energy in the form of heat and light. This process is known as combustion.
By definition raw fossil fuels are not required to be purely composed of hydrocarbons. A hydrocarbon is by definition, just hydrogen and carbon; however in fossil fuels impurities are present that are often removed in refining. Some forms of fossil fuels have little or no hydrogen present (Coal for example is nearly all Carbon). It is not uncommon to find oxygen, nitrogen, sulfur, and other mineral and chemical components in a fossil fuel outside of pure hydrocarbons. Refineries are designed to take raw fossil fuels (oil for example) and adjust those various components to meet some requirement. A good example is in gasoline and diesel fuels where octane, heptane, butane and sulfur levels can be controlled.
No, not all fossil fuels contain methane. Fossil fuels primarily consist of carbon and hydrogen, with varying amounts of other elements like sulfur, nitrogen, and oxygen. Methane is mainly found in natural gas, which is a fossil fuel, but not all fossil fuels contain methane.
All fossil fuels contain complex hydrocarbon chains comprised of hydrogen, carbon and oxygen. They also may contain nitrogen, sulfur, moisture, and noncombustible minerals.
Fossil fuels contain chemical energy.

Fossil fuels contain high concentrations of carbon and hydrogen atoms, which have a high energy content due to their strong chemical bonds. When these bonds are broken through combustion, a large amount of energy is released in the form of heat, which can be harnessed for various energy applications.
