A well-insulated furnace burns liquid ethanol, C2H;0H(1), to form gaseous carbon dioxide,CO2(g), and water vapour, H20(g). 150g of ethanol is fed into the furnace at a temperature of 25°C and

150% excess air is supplied at 120°C. The products emerge from the reactor at 1085°C. Calculate the AĤº for liquid ethanol based on the mass balance results given in the diagram below.[20 marks] C_{2} H_{5} O H(l)+3 O_{2}(g) \rightarrow 2 C O_{2}(g)+3 H_{2} O(g)
