How is nitrogen oxide formed from fossil fuels?
How is nitrogen oxide formed from fossil fuels?
When fuels are burned in vehicle engines, high temperatures are reached. At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide. When this nitrogen monoxide is released from vehicle exhaust systems, it combines with oxygen in the air to form nitrogen dioxide.
What is the product of burning fossil fuels?
When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
Why are nitrogen oxides bad?
The nitrogen oxides family can react with ammonia, VOCs, and other compounds to form PM 2.5 pollution that easily penetrates into sensitive and deep parts of the lung causing respiratory diseases like emphysema and bronchitis. NO x also can aggravate a pre-existing heart disease, leading to premature death.
How harmful is nitrogen gas?
Nitrogen is not toxic since about 78% of the air we breathe contains this gas. However, it is not harmless and it has NO SMELL. What is an Asphyxiant? A chemical (gas or vapour) that can cause death or unconsciousness by suffocation.
How is nitrogen monoxide produced in fossil fuel burning?
Oxides of non-metals tend to be acidic and in any high temperature combustion situation non-metals are oxidised to the oxide. Therefore any nitrogen (from air) or sulfur (in a fossil fuel) will undergo an oxidation reaction e.g. to give nitrogen monoxide and sulfur dioxide respectively.
Where does nitric oxide from fossil fuels come from?
In a study published in Science researchers were able to trace nitrates to their source: nitric oxide produced by fossil fuels. Scientists examined two isotopes of nitrogen found in nitrates from a Greenland ice core.
What are two major sources of nitrogen oxide?
The two major nitrogen oxides that occur are NO and NO 2. Coal and oil, two major fossil fuels, contain nitrogen. When these fuels are burnt to generate electricity, the produce a type of NO x known specifically as fuel NOx.
What are the pollutants from fossil fuel burning?
Pollutants from fossil fuel (coal, oil, gas etc.) burning in power stations and automobile transport include sulfur oxides and nitrogen oxides and these in turn through photochemical reactions can produce ozone and other harmful irritant gases.

How are nitrogen oxides released into the atmosphere?
Most of the nitrogen oxides released in the U.S. due to human activity are from the burning of fossil fuels associated with transportation and industry. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain. Major sources of nitrogen oxide emissions include:
