Atmospheric pollution chemical equations

Photochemical smog

1. NO2 reacts with sunlight = NO + O

2. O + O2 = O3

3. NO + VOCS = photochemical oxidants

4. Photochemical oxidants + O3 = photochemical smog

Ozone

O + O2 = O3

Sulfuric acid

1. SO2 + O2 = SO3

2. SO3 + H2O = H2SO4

Nitric acid

1. NO + O2 = NO2

2. NO2 + H2O = HNO3

Carbonic acid

CO2 + H20 = H2CO3

Acid rain

Combustion

C3H8 (fuel) + 5O2 = 3CO2 + 4H20

Burning of coal

C + O2 > CO2 + H2O

Burning of natural gas

CH4 + O2 > CO2 + H2O

Burning gasoline

C8H18 + O2 > CO2 + H2O
