ChemistryThe pollutants of combustionGCSEAQA Created by: tonisha_Created on: 10-01-23 19:14 Fuels such as coal and crude oil contain what? hydrocarbons 1 of 31 During combustion, what happens to the hydrogen and carbon? it is oxidised 2 of 31 fuel+oxygen always forms what? carbon dioxide and water vapour 3 of 31 The complete combustion of fuels requires what? plenty of oxygen 4 of 31 The incomplete combustion of fuels forms what? carbon monoxide 5 of 31 CARBON MONOXIDE --------------------------- Carbon monoxide is dangerous and toxic because it has no? (2) smell or colour 6 of 31 How does it damage humans? binds to haemoglobin on RBC reducing the amount of oxygen it can carry and transport around the body 7 of 31 Some fuels (e.g. coal) contain the element what? sulphur 8 of 31 During combustion, the fuels that contain sulfur _______ release sulfur ______? sulfur impurities sulfur dioxide 9 of 31 This means the sulfur has become what? oxidised 10 of 31 Where are oxides of nitrogen produced? in engines 11 of 31 What causes the nitrogen and oxygen to react? high temperatures 12 of 31 When any of these gases mix with clouds what is formed (2)? dilute sulfuric acid dilute nitric acid 13 of 31 This is basically what? acid rain 14 of 31 Acid rain can Cause ______ Kill_____ Damage______ cause corrosion kill plants damage building 15 of 31 What can it also cause if it is breathed in? respiratory problems 16 of 31 Particulates such as carbon (_____)? soot 17 of 31 Also increase the risk of what? respiratory problems 18 of 31 It also reflects? light back into space 19 of 31 This is called global ? dimming 20 of 31 SUMMARY ---------------- What are the five main pollutants? carbon dioxide sulfur dioxide nitrogen dioxide carbon monoxide particulates 21 of 31 Carbon dioxide is produced by what? the complete combustion of fuels 22 of 31 What environmental impact does carbon dioxide have? contributes to the greenhouse effect 23 of 31 Sulfur dioxide is produced by the _______ of sulfur _______ in ______ _____? produced by the oxidation of sulfur impurities in fossil fuels 24 of 31 What environmental impact does sulfur dioxide have? acid rain 25 of 31 Nitrogen dioxide is produced by the ______ of ______ in ______? by the oxidation of nitrogen in engines 26 of 31 What two environmental impacts does nitrogen dioxide (oxides of nitrogen) have? acid rain asthma 27 of 31 What is carbon monoxide produced by? the incomplete combustion of fuels 28 of 31 What impact does it have on humans? cause death 29 of 31 Particulates are unburnt _______ chain ________ in diesel ______? unburnt larger chain hydrocarbons in diesel engines 30 of 31 It can cause photo________ ______ and global ____? photochemical smog global dimming 31 of 31
