A 100.0 ml sample of 1.00 M NaOH is mixed with 50.0 ml of 1.00 M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid through which passes a calibrated thermometer. the temperature of each solution before mixing is 22.9°C. After adding the NaOH solution to the coffee cup and stirring the mixed solutions with thermometer; that the specific heat of the mixed solutions is 4.18 J/(g•°C), and that no heat is lost to the surroundings.
a) Write a balanced chemical equation for the reaction that takes place in the Styrofoam cup.
b) Calculate the enthalpy change per mole of H2SO4 in the reaction.
