Assignment A: Coal
How much CO2 is released during the combustion of 1 tonne of coal? In this example we will assume that all 'element carbon' reacts with oxygen, viz.:-
C(12) + O2(2x16) → CO2 (44)
Using the relative atomic masses of carbon (12) and oxygen (16), we can estimate that 12 kg of carbon will produce 44 kg of CO2. Therefore, each kilogram of carbon within coal will release (44/12) = 3.67 kg of CO2.
1. Calculate CO2 values (per tonne of coal) for:-
WOOD -
Lignite -
sub-Bituminous -
hv-Bituminous -
Iv - Bituminous -
Anthracite -
2. Which fuel releases the most CO2 per tonne of coal?
3. Calculate the production of electricity (in kWh) for:-
WOOD -
Lignite -
sub-Bituminous -
hv-Bituminous -
Iv - Bituminous -
Anthracite -
4. Recalculate the amount of CO2 released per kilowatt-hour of electricity generated.
WOOD -
Lignite -
sub-Bituminous -
hv-Bituminous -
Iv - Bituminous -
Anthracite -
5. Of those fuels analysed above, which do think is the optimum fuel?
6. Why?
7. If a Power Corp needs an average of 3,000 kWh, how does this impact the amount of fuel used and CO2 emisions?
8. What happens to CO2 emission and electricity generation if the coal is oxidized?

1. There are over 40 oil producing countries in the world. What percentage of world's conventional oil reserves are owned by the top 10 oil countries (Table 1). On a separate piece of paper, produce a pier chart to support your written answer?
2. Using Table 1 for your answer. What percentages of the world's oil occurs in Saudi Arabia? What percentage in the Middle East? Which og the top ten belong to OPEC? What percentage of worlds reserves are OPEC?
3. On Figure 3 draw the location of Bahrain, Kuwait, Iran, Iraq, Qatar, Saudi Arabia, UAE and the Straits of Hormuz.
4. Where do the Straits of Malacca, Turkish Straits & Suez Canaal occur? Which countries control them?
5. Why might countries such as the USA, Japan and those within Europe be concerned about who controls the Straits of Hormuz plus other maritime straits, such as Straits of Malacca, Turkish Straits & Suez Canaal?
6. (a) Using the data in Table, plot a graph or chart showing oil imported to the USA for 1973, 2002 & 2014.
(b) What has changed and why?
