10) The cooling effect of alcohol on the skin is due to its evaporation. Calculate the heat of vaporization of ethanol, C₂H₂OH. C₂H,OH (g); AH° = ? The standard enthalpy of formation of C₂H-OH (1) is -277.7 kJ/mol and that of C,H,OH (g) is 235.4 kJ/mol. C₂H,OH (1) 1 11) Hydrogen sulfide gas is a poisonous gas with the odor of rotten eggs. It occurs in natural gas and is produced during the decay of organic matter, which contains sulfur. The gas burns in oxygen as follows: 2 H₂S (g) + 3O₂ (g) 2 H₂O (1) +2 SO: (g) Calculate the standard enthalpy change for this reaction using standard enthalpies of formation. 1 12) In an experiment you fill a heavy-walled 5.00 L flask with methane gas, CH.. If the flask contains 7.13 g of methane at 19 °C, what is the gas pressure?
