If you were to combine a 200.0mL aqueous solution of 0.75M NaHCO3 with 200.0mL of 0.50M CaCl2 in a constant pressure calorimeter, what change in temperature would you measure? Assume that the heat capacity of your calorimeter depends only on the amount of water in it and use tabulated enthalpy values from your book. (Hint: be sure to work out the limiting reagent in the reaction, and therefore moles of reaction)
