1

Oil, gas, coal all contain

Hydrocarbons

2

Word equation for the burning of fossil fuels

Fossil fuel+oxygen-> Co2+ H20

3

Experiment to prove:

Fosil fuel burning -> H2O and Co2

-Candle under a funnel
-Funnel goes to test tube containing cobalt chloride/any hydrous copper sulfate in beaker full of ice water
-Funnel also leads to test tube of limewater

(C.c. Blue-> pink
A.c.s. White-> blue
L.w. Clear-> milky white)
(Test tube in ice to condense water vapour to water)

4

Greenhouse effect

Burning of fossil fuels adds to eath's Co2 layer

Co2 blocks heat

5

Fire triangle contains

Fuel
Oxygen
Heat

6

Explain how the burning of fossil fuels contribute to acid rain

Burns produces Sulfur dioxide -> mixes w/ rain sulfuric acid

Burns produces carbon dioxide -> mixes w/ rain carbonic acid

7

Explain how car exhaust add to acid rain

Produces nitrogen oxides-> nitric acid

8

How to reduce global warming and acid rain

-less fossil fuels
-encourage renewable energy
-planting trees
-fitting catalytic converters to remove pollutants from car exhaust
