10. A reaction at 45 °C has the following enthalpy and entropy: AH° = -86.6 kJ and AS = 382J/K. a. Calculate AG gros fess b. Is the reaction spontaneous at this temperature? 11. A piece of metal weighing 59.047 g was heated to 100.0 °C and then put into 100.0 g of water at 23.7 °C. The metal and water were allowed to come to an equilibrium temperature, determined to be 27.8 °C. Assuming no heat lost to the environment, calculate the specific heat of the metal. 12. A 237 g sample of molybdenum metal is heated to 100.1 °C and then dropped into an insulated cup containing 244 g of water at 10.0 °C. If the final temperature of the water and metal in the cup is 15.3 °C, then what is the specific heat of molybdenum?
