When 200.0 mL of 0.862 M HCl is mixed with 200.0 mL of 0.431 M Ba(OH)2 in a coffee cup calorimeter, the temperature of the solution increases from 21.25°C to 27.05°C. Given the specific heat of solution of 4.18 J g^-1 °C^-1 and assuming the density of each solution to be 1.00 g/mL, what is the heat reaction in kJ? What is the heat of reaction per mole of HCL in kJ/mol? The neutralization reaction is shown below. Answer: -55.3kJ/mol HCl
2HCl(aq) + Ba(OH)2(aq) ---> BaCl2(aq) + 2H2O(l)
