Which reactant is limiting? 2. You dissolve 3.0 g of CaCI) in 150.0gof water in a constant peessure calorimeter of negligble heat capacity. reaction is: CaCla)Ca" (aq) 2CT (aq) The The initial temperature of the water is 22.4 C and upon dissoluticn of the compound the semperature of the solution rises to 25.8 C.(15 points sotal) What is the heat of this reaction per mole of CaCh (molar mass 110 98 gmol), assuming the specific heat off the solution is 4.18 Jg C a b. Is the reaction exothermic or endothermic?
