Nitrogen oxides (NOx) are produced when fuels burn in vehicles due to the high temperatures in the combustion process. Nitrogen from the air combines with oxygen under these conditions, forming NOx emissions. These pollutants contribute to air pollution and can have harmful health and environmental effects.
NOx is present in exhaust fumes simply because of all ingredients in Earth's air, Nitrogen is the most abundant, therefore it is contained within an engine's cylinder during combustion.
Nitrogen is inert at ambient pressures and temperatures, however when exposed to cylinder heat and pressure, oxides of nitrogen are released, such as: nitric oxide (NO), nitrogen dioxide (NO2), and nitrous oxide (N20).
Unfortunately NOx is a major contributor to photochemical smog because it reacts with hydrocarbons to form ozone molecules.
Many. There Is A varying amount of nitrogen oxides in the car exhausts which are then released into the atmosphere and damages it.

Where does sulfur oxides and nitrogen oxides in the air come from?
Sulfur oxides and nitrogen oxides in the air primarily come from the burning of fossil fuels in vehicles, power plants, and industrial processes. When fuel containing sulfur and nitrogen is burned, these elements combine with oxygen in the air to form sulfur oxides (SOx) and nitrogen oxides (NOx), which are then released into the atmosphere.
How are nitrogen oxides formed when fuels are burned?
Nitrogen oxides are formed when fuels are burned at high temperatures in the presence of oxygen. The heat causes nitrogen and oxygen in the air to react, forming nitrogen oxides like nitrogen dioxide (NO2). These nitrogen oxides contribute to air pollution and can have negative effects on human health and the environment.
Which gas is produced when fossil fuels burnt?
When fossil fuels are burnt, carbon dioxide (CO2) is produced as a byproduct along with water vapor and other pollutants like carbon monoxide and nitrogen oxides.
How can we reduce nitrogen oxides?
Nitrogen oxides can be reduced by implementing technologies such as catalytic converters in vehicles and selective catalytic reduction systems in industrial processes to lower emissions. Additionally, using cleaner fuels and improving engine efficiency can also help reduce nitrogen oxide levels in the atmosphere.
Name four harmful substances that may be produced when fuels burn?
Carbon monoxide, nitrogen oxides, particulate matter, and sulfur dioxide are harmful substances that can be produced when fuels burn. They contribute to air pollution and have negative impacts on human health and the environment.
How are nitrogen oxides produced?
Nitrogen oxides are produced by the combustion of fossil fuels in vehicles, power plants, and industrial processes. When these fuels are burned at high temperatures, nitrogen and oxygen in the air react to form nitrogen oxides. Lightning and certain microbial processes can also contribute to the production of nitrogen oxides in the atmosphere.
What is needed for nitrogen oxides to be produced when hydrocarbon fuels are burned?
very high temperatures
Where does sulfur oxides and nitrogen oxides in the air come from?
Sulfur oxides and nitrogen oxides in the air primarily come from the burning of fossil fuels in vehicles, power plants, and industrial processes. When fuel containing sulfur and nitrogen is burned, these elements combine with oxygen in the air to form sulfur oxides (SOx) and nitrogen oxides (NOx), which are then released into the atmosphere.

When fossil fuels are burnt, carbon dioxide (CO2) is produced as a byproduct along with water vapor and other pollutants like carbon monoxide and nitrogen oxides.
How does oxides of nitrogen come into the atmosphere?
Nitrogen oxides are primarily emitted into the atmosphere through the combustion of fossil fuels in vehicles and power plants. They are also released during industrial processes and biomass burning. Once in the atmosphere, nitrogen oxides can react with other compounds to form pollution such as smog and acid rain.
How can we reduce nitrogen oxides?
Nitrogen oxides can be reduced by implementing technologies such as catalytic converters in vehicles and selective catalytic reduction systems in industrial processes to lower emissions. Additionally, using cleaner fuels and improving engine efficiency can also help reduce nitrogen oxide levels in the atmosphere.

Carbon monoxide, nitrogen oxides, particulate matter, and sulfur dioxide are harmful substances that can be produced when fuels burn. They contribute to air pollution and have negative impacts on human health and the environment.
How is nitrogen oxides created?
Nitrogen oxides are created through the combustion of fossil fuels at high temperatures, such as in vehicle engines and power plants. The nitrogen and oxygen in the air react together under these conditions to form nitrogen oxides, which can contribute to air pollution and smog.
When burning fuels - what is produced?
Carbon dioxide
Where does nitrogen oxide originate from?
Nitrogen oxides (NOx) primarily originate from combustion processes, such as in vehicles, power plants, and industrial facilities. They are formed when nitrogen and oxygen in the air react at high temperatures, such as in the combustion of fossil fuels. Other sources include agricultural activities and wildfires.
What is formed when nitrogen combines with oxygen when burning fossil fuels?
Various nitric oxides are formed.
