Thanks for the help :)
1. Describe what happens when two substances at different temperatures come into contact. Describe how the law of conservation of energy applies to this system.
2. Explain how the calorimeter works, and how you can calculate the heat given off or absorbed by the reaction being studied.
3. A calorimeter contains 500 g of water at 25°C. You place a hand warmer containing 100 g of liquid sodium acetate (NaAC) inside the calorimeter. When the sodium acetate finishes crystallizing, the temperature of the water inside the calorimeter is 32.2°C. The specific heat of water is 4.18 J/g-°C. What is the enthalpy of fusion (ΔHf) of the sodium acetate? Show your work.
Thanks!
