b. Calculate the mass of CO2 produced by the combustion of 1 kg of carbon. Give your answer to three significant figures. (4 marks) C. Assuming that the inert ash content of the coal does not produce any CO2, show that the combustion of 1 kg of the type of coal described in Table 3 will produce nearly 1.5 kg of CO2 (1 mark) d. The equation for the combustion of sulfur in air is: S + O2SO2 Show that the combustion of 1 kg of the coal described in Table 3 will produce 10 g of sulfur dioxide. (2 marks) e. The heat value (or calorific value) of this type of coal is approximately 4000 kilocalories per kg. Using the data in Appendix A3 of Energy Book 1, express this in GJ per tonne. How does your answer compare with the heat values for different types of coal shown in Figure 5.6 in Book 1 Chapter 5? (3 marks) f. Over the accounting year 2009/2010 the Dadri power station emitted 6.4 million tonnes of CO,. Using your answer to part (c) above, the data in Table 3 and assuming that power station ash has approximately the same density as water, calculate: i. the mass of coal burned over this period ii. the volume of ash produced in thousands of cubic metres.
