To many teachers (and students), assessment simply means giving students tests and assigning them grades. This conception of assessment is not only limited, but also limiting (see section below on Assessment versus grading).
Molecular weight of Nickel(II) Chloride Hexahydrate. Molar mass of NiCl2.6H2O = 237.69108 g/mol. Convert grams Nickel(II) Chloride Hexahydrate to moles or moles Nickel(II) Chloride Hexahydrate to grams. Molecular weight calculation: 58.6934 + 35.453*2 + 6*(1.00794*2 + 15.9994) Note that all formulas are case-sensitive.
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.
