Problem 1 Anna mixed 50 mol of water and 1 mol of MCl2, where M is an unspecified alkali earth metal. How much heat will be released/consumed upon addition of 1 extra mol of MCl2 dissolved in 10 mol of water to the initial liquid solution in an isothermal process? Heats of formation for 1 mol of MCl2 in water at 25C are given in the table below. Water 10 mol 15 mol 20 mol 25 mol 50 mol 100 mol 300 mol 500 mol 1000 mol Heats of formation of 1 mol of MCl2, kJ -862.74 -867.85 -870.06 -871.07 -872.91 -873.82 -874.79 -875.13 -875.54
