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 ---> Carbon Dioxide + Water + Energy 

b.      During combustion the nitrogen in air can react to form what gases?

During combustion the nitrogen combines in the air to form NOx's

c.       What condition is necessary for the formation of these gases?

For these gases to form there needs to be high temperatures to break the triple bonds.

d.      In what common object is this condition found?

In Cars.

e.      Why is this condition needed for nitrogen to react?

There needs to be high temperature to break the diatomic nitrogen molecules because they all have triple covalent bonds, and the heat breaks them up

f.        What are the dangers of the products from this reaction?

The dangers of this product is that it forms NOx's which cause cancer, asthma, lung problems and shortens people life.
