For the reaction:
2H+(aq) + CO3-2(aq) --> CO2(g) + H2O(l)

A. Calculate the deltaHºrxn for the reaction. Given deltaHºf for CO3-2(aq) = -677.1 kJ/mol.
B. Using the above reaction, what would be the final temperature of a coffee cup calorimeter when 0.104 mol of hydrochloric acid react with 0.104 mol of sodium carbonate when 0.512 pounds of the solution starts at 25.2ºC with a specific heat capacity of 4.11 cal/(g ºC)?
