250. mL of 0.600 M HCl is mixed with 250. mL of 0.600 M NaOH , resulting in a neutralization reaction with net ionic equation:
H+ (aq) + OH- (aq) → H2O(ℓ) ∆Hrxn = -57.0 kJ
Assume the solutions have specific heat capacity of 4.18 J/g C , and the solutions have a density of 1.00 g/mL.
The reaction takes place in a coffee-cup calorimeter, and all heat transfer occurs within the confines of the calorimeter.
If the initial temperature of both solutions was 25.0 C, what is the final temperature of the solution after reaction takes place?
