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?

NO - Nitrogen Monoxide

NO2 - Nitrogen Dioxide

N2O- Laughing gas

(NOx)

c.       What condition is necessary for this reaction to take place?

Very high temperatures

d.      In what common object is this condition found?

In cars

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

Nitrogen has a very strong bond (2 covalent bonds), almost impossible to separate

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

When they dissolve into water, it produces a mixture called NITRIC ACID.. which when evaporated, and rains forms ACID RAIN
