Question
You perform the following reaction in lab: CaCl2 (aq) ? Ca2+ (aq) + 2 Cl- (aq) , ?H = -81.5 kJ. Using the Styrofoam-cup calorimetry
You perform the following reaction in lab: CaCl2 (aq) ? Ca2+ (aq) + 2 Cl- (aq) , ?H = -81.5 kJ.
Using the Styrofoam-cup calorimetry set-up, a 9.2 g sample of calcium chloride is dissolved in 80.8 g of water and the temperature rises. Both substances are initially at 25.0C. Calculate the final temperature of the solution. (The specific heat capacity of the solution is 4.18 J/gC)
