Energy change in the water = mass x specific heat capacity x temperature change. Energy change = 0.1 x 4.2 x 7. Energy change = +2.94 kJ (the sign is positive because the water temperature decreases, i.e. heat is being transferred from the water to the ammonium nitrate - it is an endothermic change) Moles of ammonium nitrate = 10/80 = 0.125 moles.

Ammonium sulfate

Ammonium sulfate decomposes upon heating above 250 C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water.

Drying agents

 · Calcium sulfate (n=0.5, e=0.004 mg/L) is a neutral and good drying agent. However, it does not have a high capacity, which makes it useless for very wet solutions. The commercially available Drierite® contains about 2 % cobalt chloride as indicator, which can be leached out into various solvents i.e. ethanol, DMSO, DMF, ethers, etc. Drierite is often used in desiccators .
