3. Mixing 1.00 mL of 1.00M HNO, and 1.00 mL of 1.00 M KOH causes the temperature of the two at 21.3°Č to become 31.2°C. Calculate the heat of neutralization. 4. In a coffee cup calorimeter, the temperature of 35.0 g of water drops from 20°C to 15.6°C when 9.0 g KBr is dissolved in it. Write a thermochemical equation for this.

Activity 3.9 Answer the following. . Einanol weighing 3.56 g is burned in a constant-volume bomb calorimeter. Consequently, the temperature rises from 15.17°C to 28.52°C. If heat mol kJ capacity of the bomb plus water is 8.224 KJ find the heat of reaction in 2. A metal sample weighing 56.7 g at temperature of 98.0°C was placed in 50.0 g of water in a calorimeter at 26.5°C. At equilibrium, the temperature of water and metal was 34.6°C. What is the specific heat of the metal? 3. Mixing 1.00 mL of 1.00 M HNO, and 1.00 mL of 1.00 M KOH causes the temperature of the two at 21.3°C to become 31.2°C.
