25.0ml of a 4.21M HCL solution at 25.2C and 50.0ml of a 2.2M NaOH solution at 25.2C are reacted together to give a temperature of 44.1C. The specific heat of the solution is 3.88 J/g-degree and it weighs 76.6g. First determine which is the limiting reagent, then calculate the heat produced by the reaction (q), and molar heat of the reaction (H) using the above equations
