In a coffee-cup calorimeter, 100.0 mL of 1.0 M NaOH and 100.0 mL of 1.0 M HCl are mixed. Both solutions were origi- nally at 24.68C. After the reaction, the nal temperature is 31.38C. Assuming that

all the solutions have a density of 1.0 g/cm3 and a speci c heat capacity of 4.18 J/8C ? g, calcu- late the enthalpy change for the neutralization of HCl by NaOH. Assume that no heat is lost to the surroundings or to the calorimeter.
