Question

You would like to measure the heat of neutralization of anacid with a base. You mix 150 mL each of 0.45 M HNO3 and0.45 M NaOH, both at a temperature of 18.3 °C in a calorimetercup equilibrated to that same temperature. After following thetemperature change for 10 minutes and extrapolating it back to thetime of addition, you find that the "final temperature" aftermixing was 21.2 °C. Previously you measured the heat capacityof the calorimeter cup (Ccup) to be 43 J/°C.

Write the net ionic equation for thisneutralization reaction, including the states of matter (i.e.H+(aq)) for the reactants and products.
