Question

Please answer both questions. Thank you.

1) The temperature of a 15.0 g sample of a metal (specific heat 0.040 J/g⸳°C) is raised by 18.2°C. How much heat (in J) has been absorbed by the metal?

2)

1. A calorimeter has a heat capacity of 35.45 J/°C. When 100.0 mL of a strong acid at

23.1°C is mixed with 100.0 mL of a strong base at 23.1°C, the temperature of the solution increases to 26.2°C. Assume that the density of the solution is 1.05 g/mL and its specific heat is 4.10 J/g⸳°C. Calculate:

1. The heat absorbed by the solution

2. The heat absorbed by the calorimeter

3. The heat released by the reaction
