Answer 1

• incomplete combustion due to the lack of oxygen

Question 2

carbon monoxide effects

Answer 2

CO combines with haemoglobin in blood and reduces its ability to transport oxygen around the body

Question 3

sulfur dioxide source

chemical equation

Answer 3

power stations exhaust fumes of vehicles-combustion of fossil fuels due to to the sulfur impurities
volcanic eruptions
S(s)+O2(g)>SO2(g)

Question 4

sulfur dioxide effects

Answer 4

sulfur dioxide

acid rain-acidifies water bodies and reduces the ph of the water bodies and kills the aquatic life.

wears away limestone buildings

Question 5

nitrogen oxide source

equation

Answer 5

internal combustion of engine

lighting activity

nitrogen oxide is formed when nitrogen and oxygen react to form 2NO in high tmperatures N2(g)+O2(g)>2NO(g)

NO(g)+O2>2NO(g)
