In a "coffee cup calorimeter" 200 mL of 2.0M sodium hydroxide and 200mL of 2.0M hydrochloric acid are mixed. Both solutions were originally at 200 degrees C. After the reaction, the final temp is33.4 degrees C. Assume that all solutions have a density of 1 g/mLand a specific heat of 4.18 J/g degrees C.
a) Calculate the enthalpy change for the reaction as performed.
b) Calculate the enthalpy change for the reaction as written in the balanced equation.
