Core Chemistry Chapter 4 AQA

HideShow resource information
What are compounds in crude oil
Hydrocarbons
1 of 16
What are hydrocarbons
Molecules that contain hydrogen and carbon
2 of 16
What are saturated hydrocarbons
Hydrocarbons that have a single bond
3 of 16
Why are different hydrocarbons collected at different levels of a fractional distillation column
Different hydrocarbons have different boiling points, condense at different levels
4 of 16
What properties would you expect for a fraction that is collected one third of the way up a fractioning column
Viscous liquid, not very flammable, medium-high boiling point
5 of 16
What happens when pure hydrocarbons burn completely
They are oxidised to carbon dioxide and water
6 of 16
What is an environmental problem of sulfer dioxide and nitrogen oxide
Acid rain
7 of 16
What is produced from incomplete combustion
Carbon Monoxide
8 of 16
What are particulates
Solid particles that contain carbon and unburnt hydrocarbons
9 of 16
What causes global dimming
Tiny solid particulates that reflect sunlight
10 of 16
What are two methods used to reduce amount of sulfer dioxide prodcued by burning fuels
Removal of waste gases from power stations, removed before supplied to users
11 of 16
Name two biofuels
Biodiesel, ethanol
12 of 16
What are biofuels
Fuels made from animal/plant material
13 of 16
Give one advantage and disadvantage of hydrogen as a fuel
ad- only produces water when burnt, dis - gas so takes up large volume making it difficult to store in quantities needed fot combustion in engines
14 of 16
How to remove carbon monoxide/nitrogen oxides
Cars are fitted with catalyst converters to remove the gases
15 of 16
What happens when pure hydrocarbons burn completely
They are oxidised to carbon dioxide and water
