1 of 8
When Nitrogen is oxidised what is produced?
Nitrogen dioxide
2 of 8
Where are some carbon particulates disposed?
It is disposed on surfaces such as stone buildings making them dirty.
3 of 8
Natural processes carbon dioxide can be removed?
Photosynthesis and some dissolves in rain and seawater where is reacts with other chemicals.
4 of 8
what 2 chemicals when reacted together produce acid rain?
Sulfur dioxide and nitrogen dioxide
5 of 8
What are the effects of acid rain?
It damages trees, corrodes metal and upsets the pH of rivers causing plants and animals to die.
6 of 8
Power station emissions can be reduced by?
Using less electricity, removing sulfur and toxic chemicals from gas, oil and coal before burning and using a alternative renewable source such as wind, solar energy. You can also use wet scrubbing.
