Chemistry

Consider the reaction: 2HCl(aq) + Ba(OH)2(aq) ! BaCl2(aq) + 2H2O(l) deltaH = \"118 kJ

A) Calculate the heat produced when 700.0 mL of 0.500 M HCl ismixed with 300.0 mL of 0.500 M Ba(OH)2. Note: One of the solutionsis the limiting reagent.

B) Calculate the final temperature if both solutions wereinitially at 25.0° C, and they were mixed together in a calorimeterwith a heat capacity of 180.3 J/C° Note: The density specific heatcapacity of the solution are the same as that of water: D = 1.00g/cm3 and C = 4.184 J /g•°C
