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


a.       Write the general equation for the combustion of a fuel
Fuel + Oxygen ---> Oxides + Energy 

b.      During combustion the nitrogen in air can react to form what gases?
NOx Gases (NO or NO2)

c.       What condition is necessary for the formation of these gases?
Very High Temperature / Energy

d.      In what common object is this condition found?
Car Engines

e.      Why is this condition needed for nitrogen to react?
Because Nitrogen Exists as Diatomic Molecules and it has three strong covalent bonds which makes it
hard for the bonds to break

f.        What are the dangers of the products from this reaction?
It could cause asthma and it could also shorten people's life by 9 years. Also it could erode plants and
animals due to the formation of Acid Rain which is dangerous
