Pollutants

Cards (12)

What is a major source of pollutants?
The combustion of fuels
What fuels contain sulfur carbon and/or hydrogen?
Most fuels including coal
how is Carbon dioxide produced
Complete combustion in excess of oxygen of fuel containing carbon like coal crude oil(hydrocarbons)
CH4 +2O2->CO2+H2O
Carbon dioxide environmental impact
Greenhouse gas too much can lead to global warming
How is Carbon Monoxide (CO) produced
Incomplete combustion (in limited supply of oxygen of fuel
Carbon Monoxide (CO) environmental impact
Toxic gas- combines with red blood cells (the haemogoblin in then and reduce the oxygen carrying capacity of blood
How is Carbon (soot)/particulates produced
CH4+O2—>C+2H2O
Carbon (soot)/particulates environmental impact 
Global dimming
Respiratory problems
How is it sulphur dioxide (SO2) produced
Fuel containing sulfur impurities like coal is burned
S+O2->SO2
Sulfur Dioxide (SO2) environmental impact
Acid rain
Destroys leaves and plants
Corrodes limestone building
Increases acidity of soil and lakes-kills fish
Respiratory problems
how is Nitrogen Oxides (NOx)or NO2 NO3 produced
High temperature in car engine
Nitrogen reacts with oxygen
N2+O2—>2NO
N2+2O2—>2NO
Nitrogen Oxides (NOx)
Acid rain
Destroys leaves and plants
Corrodes limestone building
Increases acidity of soil and lakes-kills fish
Respiratory problems
