Question

A styrofoam calorimeter contains 60.0 mL of 0.750 M H₃C₆H₅O₇ at 22.8^oC. When 9.83 g NaHCO₃ is added to the calorimeter, the temperature of the resulting solution decreases to a minimum of 5.1^oC. The reaction that occurs is:

H₃C₆H₅O₇(aq)+3NaHCO₃(aq)→Na₃C₆H₅O₇(aq)+3CO₂(g)+3H₂O(l)

ΔHreaction=???
