Nitrogen and oxygen can react to form oxides of nitrogen. The reaction can occur whenever a combustion reaction takes place in the presence of nitrogen. It could take place in a car engine because it is where fuel combusts and the temperature within engines can be high. The products formed are NO (nitric oxide) and NO2 (nitrogen dioxide) which are of harm to the environment.

What type of matter is a car exhaust?
Car exhaust is particulate matter. Other examples of particulate matter are swirls of dust being blown in the wind, and the soot and ashes from a campfire.
How are nitric oxide and sulfur dioxide involved in acid deposition?
These gases form acids (sulphuric and nitric acidsrespectively) by reacting with oxygen an water present in air the first rain of the season contains droplets of these acids and effect the all material which is hit by such rain.
When people burn fossils fuels do they send oxygen into the air?
No, burning fossil fuel takes free oxygen from the air. The fuel contains carbon and hydrogen, and the burning process unites carbon with oxygen, and also hydrogen with oxygen. Both these chemical process produce a lot of heat, which is used to drive a heat-engine, which can be a gasoline or diesel engine or a steam turbine or a gas turbine.The formation of these chemical bonds generates CO2 and H2O, also known as carbon dioxide and water, which are the major products of burning fossil fuel. In round numbers, burning 1 kg of fuel takes 3.5 kg of oxyen from the air, and generates 3.1 kg of CO2 plus 1.4 kg of water; and about 50 MJ of heat energy is generated.In the average car engine, about 25% of the heat energy produced is converted into mechanical energy to drive the car.
How do you make a car run on hydrogen?
It's just called a modified engine. But the device used to convert hydrogen and oxygen into water is called a fuel cell, so that's probably what cars that run on hydrogen gas use to operate.
Is car exhaust a primary pollutant What about acid precipitation or smoke from a factory or fumes from burning plastic?
Car exhaust contains primary pollutants like carbon monoxide and nitrogen oxides, which are emitted directly into the atmosphere. Acid precipitation is caused by secondary pollutants, such as sulfur dioxide and nitrogen oxides, which react with water in the atmosphere to form sulfuric acid and nitric acid. Smoke from a factory and fumes from burning plastic can contain a mix of primary and secondary pollutants depending on the specific chemicals released during combustion.
Why can oxygen and nitrogen react together in a car engine?
In a car engine, oxygen and nitrogen from the air can react due to the high temperatures created during combustion. Nitrogen oxides (NOx) are formed as a byproduct of this reaction, which is a contributor to air pollution.
Why can nitrogen and oxygen combine inside a car engine?
Nitrogen and oxygen can combine inside a car engine due to the high temperatures reached during combustion. This leads to the formation of nitrogen oxides (NOx) as a byproduct. Nitrogen and oxygen in the air react with each other under these conditions to produce NOx emissions.
How is nitrogen produced in a car engine?
Nitrogen is produced in a car engine primarily as a byproduct of the combustion process. During combustion, air is drawn into the engine, which contains about 78% nitrogen. When the fuel burns, the high temperatures can cause some nitrogen to react with oxygen, forming nitrogen oxides (NOx), but most of the nitrogen remains unreacted and is expelled through the exhaust. Thus, while nitrogen itself is not generated in a car engine, it is present in the air used for combustion and released with the exhaust gases.
What are 2 conditions in which nitrogen will react with oxygen?
One condition is heat. This is why oxides of nitrogen (NOx) are sometimes formed in car engines where the temperature is high. Another condition is the presence of a suitable catalyst which will lower the activation energy required for the reaction to occur.
How is nitrogen dioxide formed in a car?
Nitrogen dioxide is formed in a car's engine when nitrogen oxide (NO) reacts with oxygen (O2) in the presence of heat and pressure. This reaction takes place during the combustion process of fuel in the engine, resulting in the production of nitrogen dioxide as a byproduct.
How is oxygen formed in a car engine?
Oxygen and petrol or diesel is burned in a car engine, it is not formed
What is the oxygen sensors purpose on car engine?
The sensor reads if the engine is burning too rich or too lean by reading the ratio of oxygen and nitrogen oxide. It then tells the computer to adjust the air/fuel mixture for better performance and less pollution.
What gas is pumped in racing car tires?
Nitrogen and oxygen = Air
How much energy does a car engine have?
A car engine is technically a heat engine that has no energy of its own but it converts the chemical energy in the fuels into heat and then into kinetic energy by turning a rotating shaft. The chemicals that react to make the engine work consists of carbon and hydrogen from the gasoline in the fuel tank, and oxygen taken from the atmosphere. The carbon reacts with oxygen to produce carbon dioxide and heat, while the hydrogen reacts with oxygen to produce water and heat.
What gas does car tires use?
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
Why does oxygen come out of a car exhaust?
Oxygen which comes out of a car exhaust is a product of reaction in the catalytic converter. In the catalytic converter, oxides of nitrogen undergo reactions to form less harmful nitrogen gas and oxygen, which are then expelled through the exhaust system.
Why is nitrogen dioxide not formed in a car engine?
because of combustion
