Nitrogen oxides are a common gaseous pollutant found in the exhaust from equipment that burns fuels at high temperatures like car engines of industrial heaters. They contribute to acid rain, participate in ground level ozone formation or directly injure plants.
They can be minimized by removal systems like the catalytic treatment provided in automobiles or wet scrubbers and other treatments at industrial sites. They can be reduced by the control of temperature and pressure in larger heaters and the proper control of air and fuel types.
What else can I help you with?
Why is large scale generations of sulfur oxides easier to control than the generation of nitrogen oxides?
Large scale generation of sulfur oxides is easier to control than the generation of nitrogen oxides because sulfur oxides can be removed from emissions using flue gas desulfurization systems, whereas removing nitrogen oxides requires more complex and expensive technologies like selective catalytic reduction. Sulfur oxides are also heavier than nitrogen oxides, making them easier to capture and control.
What is the symbol for nitrogen oxides?
Generally used: NOx
What nitrogen oxides have the same empirical formula?
The nitrogen oxides that have the same empirical formula are nitric oxide (NO) and nitrogen dioxide (NO2). Both have a 1:1 ratio of nitrogen to oxygen atoms.
Nitrate reduction test what does the presence of gas indicate?
if you look up the term Denitrification The formation of gaseous nitrogen and/or oxides of nitrogen from nitrate or nitrite by certain bacteria during ANAEROBIC RESPIRATION. Denitrification only occurs in ANAEROBIC or MICROAEROPHILIC conditions when there is sufficient organic carbon to support reaction. Denitrification may be used as a treatment technology to remove nitrogen oxides from liquid waste streams.
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 are 2 ways that nitrogen can be removed from the atmosphere?
Nitrogen can be removed from the atmosphere through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Nitrogen can also be removed through lightning strikes, which can combine nitrogen molecules with oxygen to form nitrogen oxides that are washed out of the atmosphere by rain.
What is the formation of oxides of nitrogen and eventually nitrates as nitrogen fixing?
Reactions for the formation of oxides of nitrogen and nitrates as nitrogen fixing
Why is large scale generations of sulfur oxides easier to control than the generation of nitrogen oxides?
Large scale generation of sulfur oxides is easier to control than the generation of nitrogen oxides because sulfur oxides can be removed from emissions using flue gas desulfurization systems, whereas removing nitrogen oxides requires more complex and expensive technologies like selective catalytic reduction. Sulfur oxides are also heavier than nitrogen oxides, making them easier to capture and control.
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.
What is the symbol for nitrogen oxides?
Generally used: NOx
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.
What gases react to make nitrogen oxides?
Nitrogen oxides are typically formed when nitrogen and oxygen react together at high temperatures in combustion processes, such as in vehicle engines or industrial machinery. Nitrogen and oxygen are the main gases involved in the formation of nitrogen oxides.
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.
What is the term for damaging precipitation caused by oxides of sulfur and nitrogen?
Acid rain is the term for damaging preciptation caused by oxides of sulfur and nitrogen.
What nitrogen oxides have the same empirical formula?
The nitrogen oxides that have the same empirical formula are nitric oxide (NO) and nitrogen dioxide (NO2). Both have a 1:1 ratio of nitrogen to oxygen atoms.
What is NO means in emission test?
Nitrogen oxides
