What is coal ?
it is mainly Carbon
1 of 19
What are mainly compounds of hydrocarbons ?
Petrol, diesel fuel, fuel oil
2 of 19
What is a hydrocarbon ?
A molecule made up of only carbon and hydrogen atoms
3 of 19
when fuels burn, atoms of carbon and/ or hydrogen from the fuel combine with oxygen fro the air to produce.....
carbon dioxide and/or water (hydrogen oxide)
4 of 19
What is it called when substances chemically combine with oxygen ?
oxidation
5 of 19
What is it called when substances loose oxygen
reduction
6 of 19
What do combustion reactions involve ?
they involve oxidation
7 of 19
When do fuels burn more rapidly ?
In pure oxygen rather than in air
8 of 19
What are the properties of the reactants and products in a chemical reaction
they are all different
9 of 19
What happens to atoms in a chemical reaction?
They are rearranged
10 of 19
What happens to the number of atoms at the start (the reactants) and at the end (the products) in a chemical reaction?
nothing is gained nor lost ( the conservation of mass)
11 of 19
What pollutants are caused when burning fossil fuels in power stations and in transport
carbon dioxide, sulfur dioxide, nitrogen oxides, carbon monoxide, particulate carbon
12 of 19
What pollutants are caused when burning fossil fuels in power stations and in transport (incomplete combustion)
carbon monoxide, particulate carbon
13 of 19
When is Nitrogen monoxide formed ?
during the combustion of fuels in air
14 of 19
methane +oxygen ------>
carbon dioxide +water
15 of 19
air (nitrogen+oxygen) + fuel (mixture of hydrocarbons)----->
carbon dioxide, water, nitrogen, carbon monoxide, nitrogen monoxide, carbon particulates
16 of 19
Where do atmospheric pollutants go ? carbon
particulate carbon is deposited on surfaces, making them dirty
17 of 19
Where do atmospheric pollutants go ? Sulphur dioxide and Nitrogen dioxide
react with water and oxygen to produce acid rain
18 of 19
Where do atmospheric pollutants go ? Carbon dioxide
used by plants to photosynthesis, dissolves in rain water and in sea water
