5.11 I can recall how nitrogen oxides are formed in car engines




1)Write the general equation for the combustion of a fuel
fuel + oxygen --> carbon dioxide + water + energy

2)During combustion the nitrogen in air can react to form what gases?
The nitrogen combust to from NOX gases

3) What condition is necessary for the formation of these gases?
Extremely high temperatures are needed for the formation of these gases

4)  In what common object is this condition found?
a car engine

5) Why is this condition needed for nitrogen to react?
Nitrogen molecules are bonded together with a triple covalent bond and are therefore inert. High temperatures are needed to break this strong bond

6)  What are the dangers of the products from this reaction?
You may be subjected to asthma and other diseases. It can also produce acid rain which is corrosive.
