When 50.0 mL of 1.24 M of HCI(aq) is
combined with 50.0 mL of 1.32 M of
NaOH(aq) in a coffee-cup
calorimeter, the temperature of the
solution increases by 8.0 °C. What
is the change in enthalpy for this
balanced reaction?
HCl(aq) + NaOH(aq) → NacI(aq) + H2
O(); Assume that the solution
density is 1.00 g/mL and the
specific heat capacity of the
solution is 4.18 J/g?°C)
a. -52.7 kJ
O b. -55.3 kJ
O C. -56.7 kJ
O d. -53.9 kJ
O e. -57.8 kJ
