Yes, when they are burnt.
Burning coal (a fossil fuel) releases carbon dioxide and sulphur dioxide.
Fossil fuel (hydrocarbon) + oxygen -> carbon dioxide + water + energy
When fossil fuels burn, oxygen is used as the gas that reacts with the carbon in the fuel to produce carbon dioxide. This process is known as combustion and is the reason why carbon dioxide is released as a byproduct of burning fossil fuels.
No, formation of fossil fuels (coal, oil and natural gas) removes carbon dioxide from the atmosphere.Burning of fossil fuels releases carbon dioxide.
carbon dioxide
Fossil fuels such as coal, oil, and natural gas produce carbon dioxide when burned in combustion processes. Wood and biomass also produce carbon dioxide when burned. These activities contribute to the greenhouse effect and global warming.
Fossil fuel + Oxygen gas > Carbon dioxide + water + heat (apex)
Coal is known to produce more carbon dioxide when burned compared to any other fossil fuel. This is due to its high carbon content and lower energy efficiency.
Coal is the fossil fuel that emits the most carbon dioxide when burned, due to its high carbon content compared to other fossil fuels like oil and natural gas.
oil
Yes, carbon dioxide is a gas that is produced when fossil fuels are burned. Fossil fuels such as coal, oil, and natural gas release carbon dioxide into the atmosphere when they are used for energy production.
Diesel oil is a fossil fuel.Bio diesel oil is a renewable fuel that adds to carbon dioxide to the greenhouse gases (it moves carbon dioxide in and out of the atmosphere as part of the carbon cycle).
