j0104528resize.gif(a) Burning in power stations or in transport systems, whether gas, oil or coal, produces huge quantities of gas which is considered to cause .
(b) If a fossil fuel contains sulfur, on combustion the fuel the sulfur burns to form .

toxic.gif(c) The pollutants and particulate are formed from the incomplete burning of a fuel. The gas carbon monoxide is highly and particles of carbon makes surfaces .

(d) Nitrogen oxides are formed from the reaction between atmospheric and at the high temperatures inside e.g. car engines.

(e) Given the following six molecular structures ...
(i) O=C=O, (ii) O=S=O, (iii) N=O, (iv) H-O-H, (v) C=O and (vi) O=N=O

j0223682.gifcarbon monoxide CO is molecule and formed in the combustion of fossil fuels e.g. car engines.

water H2O is molecule and the second biggest product of fossil fuel combustion.

acidrain1.gifnitrogen dioxide, NO2 is molecule and is formed in the atmosphere by the oxidation of molecule . and dissolves and reacts with water to cause .

carbon dioxide CO2 is molecule , it dissolves in rain water or sea water and can make the oceans too but is used by plants in .

hws8.gifsulfur dioxide SO2 is molecule and reacts with oxygen (from air) in water to also cause which can make lakes and rivers becoming too acid harming wildlife.

nitrogen monoxide NO is molecule and formed in combustion situations and is to molecule by reaction with oxygen in the atmosphere.
