3) You would like to measure the heat of neutralization of an acid with a base. You mix 225 mL each of 0.65 M HNO, and 0.65 M LiOH, both at a temperature of 18.1 °C in a calorimeter cup equilibrated to that same temperature. After following the temperature change for 10 min and extrapolating it back to the time of addition, you find that the "final temperature" after mixing was 22.3 °C. Previously, you measured the heat capacity of...

The reaction of an acid such as HCl with a base, such as NaOH, in water is an exothermic reaction. HCl(aq) + NaOH(aq) ---> NaCl(aq) + H2O In one experiment, a student placed 55.0 mL of 1.00 M HCl in a coffee-cup calorimeter and carefully measured its temperature to be 35.5oC. To this was added 55.0 mL of 1.00 M NaOH solution whose temperature was also 35.5oC. The mixture was quickly stirred, and the student noticed that the temperature of...
