CuCl 2 : Molar mass: 134.45 g/mol (anhydrous) 170.48 g/mol (dihydrate) Appearance dark brown solid (anhydrous) light blue solid (dihydrate) Odor: odorless
Calcium chloride was apparently discovered in the 15th century but wasn't studied properly until the 18th century. [11] It was historically called "fixed sal ammoniac" (Latin: sal ammoniacum fixum [12]) because it was synthesized during the distillation of ammonium chloride with lime and was nonvolatile (while the former appeared to sublime); in more modern times (18th-19th cc.) it was called ...
IR absorption spectrum of copper(I) chloride. Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl.The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid.
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.

If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1329 ahead. Let's start with a few hints.
Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...
