A 65.0 mL sample of 1.0 M NaOH is mixed with 48.0 mL of 1.0 M
H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid
through which passes a calibrated thermometer. The temperature of
each solution before mixing is 24.4°C. After adding the NaOH
solution to the coffee cup, the mixed solutions are stirred until
reaction is complete. Assume that the density of the mixed
solutions is 1.0 g/mL, that the specific heat of the...
