If 52.3 g of argon at 351 K is compressed isothermally and reversibly from a pressure of 1.97 atm to 4.37 atm, calculate the work done on the gas and the heat absorbed by the gas in the process. What are the changes in energy (AU) and in enthalpy (AH) of the gas? The standard enthalpy change of combustion (to CO2(g) and H20()) at 25°C of the organic solid decanoic acid, C10H2002(s), is determined to be -6060.3 kJ/mol. What is the standard enthalpy of formation (AH_f°) of C10H2002(s) based on this value? Use the following data: AH_f° H2O(l) = -285.83 kJ/mol; AH_f° CO2(g)=-393.51 kJ/mol. A piece of solid bismuth weighing 27.7 g at a temperature of 253 °C is placed in 277 g of liquid bismuth at a temperature of 333 °C. Calculate the final temperature after thermal equilibrium is reached, assuming no heat loss to the surroundings. The enthalpy of fusion of solid bismuth is AH_fus = 11.0 kJ/mol at its melting point of 271 °C. The molar heat capacities C_P of solid and liquid bismuth are 26.3 and 31.6 J/K-mol, respectively. ||| כ
