GASES IN THE AIR
- nitrogen (N2) DIATOMIC GASES (2 atoms) SINGLE ATOMS = all of Group 0
- oxygen (O2) - nitrogen
- carbon dioxide (CO2) - oxygen
- argon (Ar) - hydrogen
- water vapour (H2O) - all group 7
POLLUTANTS FROM BURNING FOSSIL FUELS
SUBSTANCE FORMED HOW IT IS FORMED POTENTIAL PROBLEMS SOLUTIONS
UNBURNED FUELS un simple combustión Harmful and a greenhouse Ensure correct fuel:air mixture
gas when fuel is burned
SULFURIC DIOXIDE Combustion of S (reaction with oxygen) in fuel Acid rain Remove S from fuel before
SO2 burning;
NITROGEN OXIDES Reaction of N2 in air with O2 in air at very high Acid rain use a catalytic converter
NO / NO2 temperatures (often in engines or furnaces)
SOOT / PARTICLES tens to thousands of primary carbon particles
WATER H20 oxidation of hydrogen in hydrocarbon fuels
CARBON DIOXIDE Complete combustion (reaction with oxygen) of Greenhouse gas causing Burn less fossil fuels
CO2 C in fuel global warming
CARBON MONOXIDE Incomplete combustion (reaction with oxygen) Toxic Ensure there is a good supply of
CO of C in fuel air/oxygen when burned
