Use the cell potential for the Pb-PbI2 cell and the known [Pb2+] to calculate the [Pb2+] in equilibrium with PbI2.
suppose 45.0g of water at 85 C is added to 105.0 g of ice at 0 C. The molar heat of fusion of water is 6.01 kJ/mol, and teh specific heat if water is 4.18 J/g C. on this basis of these data (a) what will be the final temperature of the mixture and..
