50 mL of a 0.28 mol/L solution of ammonia at 19.6 degrees Celsius was added to 100 mL of a 0.14 mol/L solution of nitric acid also at 19.6 degrees Celsius. The final temp. was 20.7 degrees Celsius. Write a net ionic equation for the reaction taht occurred. Making the same assumptions and using the same values for density and heat capacity as in the other question, calculate the enthalpy change for this reaction.
