If 100.0 g of ice at -10.0C is placed in 200 g of water at 90.0C in an insulated container, what will be the temperature of the system when equilibrium is established? (Sp. heat of H20(s) = 2.09 J/g C, Sp. heat of H2O(l) = 4.18 J/g-C, heat of fus. of HO(s) = 333 J/g. O 31.8 C O O O 65 C 27 C 20 C 72 C
