HYdrocarbons mainly - Hydrogen and carbon. However also oxygen and impurities such as sulfur
Carbon, Hydrogen, Oxygen & Nitrogen.
Carbon and hydrogen
Coal oil is only found in cannel coal and bituminous shale coal.
Coal is a solid. Oil is a liquid Natural gas is gas Oil shale is a rock Peat is squishy.
Most coal and oil are natural and is extracted from the earth. Most coal and oil are natural and is extracted from the earth.
Carbon, hydrogen, and oxygen mainly, with impurities such as sulfur which are not part of the energy produced and are generally undesirable
water+coal=oil
Yes, both coal and oil contain small quantities of lead, but not very much- about 1%.
Because they contain oil and coal things such as these.
Uranium - it is a radioactive element. Natural gas, coal and oil are all decomposition products of ancient life.
Carbon
Carbon and hydrogen
Carbon, Hydrogen, Oxygen & Nitrogen.
They are substances so they are not forms of energy. They contain chemical energy.
Crude Oil, Ethanol ( Alcohol ), Fossil Fuels.
oil alternative is carrots, apples, and other fruits
Paleontologists recognize rock strata that may contain oil, natural gas, coal, and other resources which are valuable. Same for geologists.
