1. An instant heat pack uses a chemical reaction to produce heat. Explain the general chemistry behind the heat production by the heat pack. Also describe the application of the law of conservation of energy to the heat pack and the surrounding environment.
2. For an experiment, you have a calorimeter with 350 g of water at 24°C. 175 g of crystalline ammonium nitrate from a cold pack is placed into the calorimeter. When the ammonium nitrate finishes dissolving in the water, the temperature of the water inside the calorimeter is 5.5°C. The specific heat of water is 4.18 J/g °C.
3. What is the enthalpy of dissolving (DHdissolving) of the ammonium nitrate in J/g? Make sure to clearly show all of your work. You may need to use q = mΔHdissolving.You can use a calorimeter to find the specific heat of an object. Explain the steps involved and how to calculate the specific heat of a substance.
