Below, you're give two chemical reactions important in the steel industry. The first is used to form carbon oxide and to provide heat for some of the other processes. The second uses carbon oxide to transform iron ore into iron.

2C  +  O2   à  2CO  +  110.5 kJ

3CO  +  Fe2O3  +  26.8 kJ   à  2Fe  +  3CO2

a)   Calculate the quantity of heat given off during the reaction of 1.0 t of coal (coke) with oxygen.                                                         4 marks

2C  +  O2   à  2CO  +  110.5 kJ

1t = 106g  

1 x 106 g / 12.01g/mol = 8.33 x 104 moles
