4. (30 points) 50.0 g of ice at -10 C is added to 900 g of H20 (1) at 90 C. The process is carried out in an isolated container under constant pressure of 1 bar. Calculate the final temperature of the system and AS for the overall process. Is the process spontaneous or not? The heat capacities and enthalpies are given in the following: C-CH2O()) = 75.3 J K-'mol' and CP(H2O(s)) = 37.7 J K 'mol, AH fusion=6 kJ mol' at 0 C. Molecular weight of water is 18 g mol-' (Hint: assume constant heat capacities in this problem)
