The health care costs of obesity in the U.S. were estimated to be as high as $190 billion in 2005, (2) a number that is double earlier estimates, and that is expected to rise, along with obesity rates, over the coming decades. This includes money spent directly on medical care and prescription drugs related to obesity.
Ferric chloride is a red-orange solid that has hygroscopic properties. Chemical Formula: FeCl 3. Layman's explanation: Ferric chloride is a corrosive chemical, thus, it is used to deodorize sewage and industrial waste by partially reducing to ferrous chloride.It is also employed as an engraving reagent on metal surfaces. Other applications include its use as a flocculating agent in water treatment.hemical Formula: FeCl 3.

This releases energy (heat of hydration or heat of solution) which further separates the ions in the solid (held together by the lattice energy). Calcium chloride is not only soluble, it is hygroscopic (meaning that it will actually pull water out of moist air).hen picture water molecules pulling on the Ca and Cl. If the pull by the water molecules on Ca and Cl is greater than the pull by the Ca and Cl on each other then the CaCl2 will dissociated into hydrated ions in solution.
