Environmental Problems + Fossil Fuels Flashcards
1
Q
How is carbon dioxide produced
A
Complete combustion hydrocarbons
2
Q
What does sulfur dioxide cause
A
Acid rain
3
Q
How are nitrogen oxides produced
A
In hot car engines, nitrogen and oxygen from the air, react together. Nitrogen oxides formed dissolve in water to form acid
4
Q
What is the problem with carbon dioxide
A
Greenhouse effect (traps heat)
5
Q
How is sulfur dioxide produced
A
Sulfur is found as an impurity in fuels
When it is burned it forms SO2 (sulfur dioxide)
S+ O2 -> SO2, which dissolves in water to make sulphuric acid
6
Q
What problem do nitrogen oxides cause
A
Acid rain
Converted to nitric acid
7
Q
Crude oil
A
Non renewable
