CH5OH() + 3 O2(g)  2 CO(g) + 3HO(g) AH comb = -1270 kJ/mol,xn Ethanol, CH5OH, combusts in air according to the equation above. (a) Is O(g) oxidized or reduced in the reaction? Justify your answer in terms of oxidation numbers. (b) When a sample of CH5OH is combusted, the volume of CO(g) produced is 18.0 L when measured at 21.7 C and 1.03 atm. Determine the number of moles of CO(g) produced. (c) Determine the volume of CH5OH(), in mL, combusted to produce the volume of CO(g) collected in part (b). (The density of CH5OH() is 0.79 g/mL, and its molar mass is 46.1 g/mol.) (d) Determine the amount of heat, in kJ, released by the combustion reaction. (Note: part (d) is review material from Ch. 8 last year and a preview of upcoming material in Ch. 7 this year.) The combustion reaction occurred in a closed room containing 5.5610 g of air originally at 21.7C. Assume all the heat produced by the reaction was absorbed by the air (specific heat = 1.005
