If 60.0 g Copper at 85C were added to 60.0g ethanol at 10C in a calorimeter of heat capacity 30.0J K -1, what would the final common temp be assuming no heat loss? Use Cp for ethanol = 60.0 J K -1 mol -1 and Cp for Copper = 0.380 J K -1 g -1.
The equilibrium constant Kp is measured (at an unspecified temperature) to be 0.66 for the reaction:
