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.
Ammonium chloride, an inorganic compound with the formula NH 4 Cl, is a white crystalline salt, highly soluble in water. Solutions of ammonium chloride are mildly acidic. Sal ammoniac is a name of the natural, mineralogical form of ammonium chloride.The mineral is commonly formed on burning coal dumps, due to condensation of coal-derived gases.It is also found around some types of volcanic vents. 5% by weight solution of ammonium chloride in water has a pH in the range 4.6 to 6.0. Some of ammonium chloride's reactions with other chemicals are endothermic, for example its reaction with barium hydroxide, and its dissolving in water.
