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.

How does carbon end up in fossil fuels?
Fossil fuels (coal, oil natural gas, peat) are made from ancient plant and animal life. Plants and animals are mde from carbon compounds. As a consequence, fossil fuels contain carbon.
What substances are fuels made of?
Fuels are made of Carbon and Hydrogen bound together as chemicals. The bonds in these chemicals store energy which is released when the fuels are burned in Oxygen.
How is hydrogen made commercially?
Currently, Hydrogen is produced commercially by reforming natural gas or other fossil fuels. The remaining gases are vented and the hydrogen remains.
What materials make fossil fuels?
Fossil fuels are organisms that lived hundreds of millions of years ago. As these plants, animals, and other organismsdied, their remains piled up. Over time, heat and pressure changed the material into other substances, including coal, oil, and natural gas. Fossil fuels are also made of hydrocarbons=energy-rich chemical compounds that contain carbon and hydrogen atoms.
What are the differences between fossil fuels and nuclear fuels?
fossil fuel is made by the nature and nuclear fuel is not made by the nature
What two elements are fossil fuels made up of?
carbon and hydrogen
How do fossil fuels release carbon dioxide into the atmosphere for 6th graders?
Fossil fuels are mainly made up from hydrogen and carbon atoms. When you burn them the oxygen in air chemically reacts with the hydrogen and carbon to produce carbon dioxide and water.
How do fossil fuels release carbons into the atmosphere?
As fossil fuels are made up of Carbon and Hydrogen. This burns in oxygen (in air) to form Carbon dioxide and Water, so the carbon dioxide is released into the air
How does carbon end up in fossil fuels?

Are nuclear fuels made of carbon and hydrogen atoms?
no
How do fossils fuel release carbon dioxide into the atmosphere?
As fossil fuels are made up of Carbon and Hydrogen. This burns in oxygen (in air) to form Carbon dioxide and Water, so the carbon dioxide is released into the air
What is all fossil fuels made of?
Fossil fuels are made up of compounds called hydrocarbons. Fossil fuels are fuels that come from natural resources, such as dead organisms.
What are the elements that hydrocarbons are made up of?
Hydrogen and Carbon - as the name suggests! They are made up of just hydrogen and carbon atoms. Hydrocarbons in fossil fuels come from the organic matter of organisms which lived 300 million years ago under conditions of extreme pressure and temperature.
What are the main fossil fuels?
There are three different types of fossil fuels and they are:crude oil,natural gas andcoal.Fossil fuels are made of the remaining bodies of prehistoric creatures and plant matter.Some would include oil shale and bituminous sands, although current commercial production is minor.
What substances are fuels made of?
Fuels are made of Carbon and Hydrogen bound together as chemicals. The bonds in these chemicals store energy which is released when the fuels are burned in Oxygen.
Is all electricity made from fossil fuels?
no electricity is made from fossil fuels.
How is hydrogen made commercially?
Currently, Hydrogen is produced commercially by reforming natural gas or other fossil fuels. The remaining gases are vented and the hydrogen remains.
