Enthalpy: Heat of Neutralization
LE39O
5. A calorimeter has a heat capacity of 35.45 J/°C.When 100.0 mL of a strong acid at 23.1°C
is mixed with 100.0 mL of a strong base at 23.1°C, the temperature of the solution increases
to 26.2°C. Assume that the density of the solution is 1.05 g/mL and its specific heat is
TAMIN9XE
4.10 J/g-°C. Calculate:
a) The heat absorbed by the solution
enoiteonD yoteodeler
b) The heat absorbed by the calorimeter
c) The heat released by the reaction
d) If the acid-base neutralization produces 0.43 mole of water, what is the enthalpy change
of the reaction (heat of neutralization), AH, in kJ/mol?
