Air Polloution

Question 1

What’s the equation for complete combustion

Answer 1

Hydrocarbon + plenty of oxygen —-> water + carbon dioxide

Question 2

What 2 pollutants does incomplete combustion form

Answer 2

Particulates (soot)
Carbon monoxide

Question 3

When does incomplete combustion occur

Answer 3

When there is not encouru oxygen available

Question 4

What are problems with particulates (soot)

Answer 4

If inhaled they can get stuck in your lungs and damage them (respiratory problems)
Cause smog (reflects sunlight back into space contributes to global warming)

Question 5

What are problems with carbon monoxide

Answer 5

• If we breath carbon monoxide it diffused into our blood and binds to Haemoglobin- can carry less oxygen
  Therefore less oxygen gets transported round the body
• it’s colourless and odourless (hard to detect)

Question 6

What are causes of carbon monoxide poisoning

Answer 6

Fainting
Coma
Death

Question 7

How are sulfur dioxides produced

Answer 7

When hydrocarbons are burned they can have impurities eg sulfur
which then gets oxidised to firm sulfur dioxide

Question 8

How are nitrogen oxides formed

Answer 8

Nitrogen and oxygen from the air react together
(Doesn’t normally happen as it requires really high temperatures)

Question 9

Problems with both sulfur dioxide and nitrogen oxides

Answer 9

When breathed in they damage our lungs (respiratory problems)
As they mix with clouds they dissolve form dilute sulfuric/nitric acid (acid rain)

Question 10

What does acid rain do as it falls

Answer 10

Damages buildings and statues
Corrodes metals
Damages plants
