Calorimetry part 8

Question

A 52.19 mL sample of 3.02 M CuSO4 reacts with 54.48 mL of 2.87 M KOH in a coffee cup calorimeter to form Cu(OH)2(s) and K2SO4 (aq). The initial temperature is 18.5°C and the final temperature is 44.9°C. Assume that the mixture has the same specific heat as water and the same density as water. Specific heat of water is 4.184 J/g-K.

h.) Is the reaction exothermic or endothermic?

Answer 1

Because the temperature went UP from 18.5 degrees to 44.9 degrees, this means heat was given off by the reaction (system) to the surroundings. This makes tge reaction EXOTHERMIC.
