10.From the following heats of combustion,CH3OH(l) + 3/2O2(g)CO2(g) + 2H2O(l)ΔHorxn= –726.4 kJ/molC(graphite) + O2(g)CO2(g)ΔHrxn= –393.5 kJ/mol 2(g) + ½O2(g)H2O(l)orxn= –285.8 kJ/mol Calculate the enthalpy of formation of methanol (CH3OH) from its elements. o H ΔH 11.Methanol (CH3OH) is an organic solvent and is also used as a fuel in some automobile engines. From the following data, calculate the standard enthalpy of formation of methanol: (5 points) 12.A 44.0 g sample of unknown metal at 99.0 °C was placed in a constant-pressure calorimeter, with a heat capacity of 12.4 J/°C, containing 80.0 g of water at 24.0°C. The final temperature of the system was found to be 28.4 °C. Calculate the specific heat of the metal. (10 points) 4 Copyright © 2014 by Thomas Edison State College. All rights reserved.
