2019/12/12· Copper is insoluble in water (H2O) as well as isopropanol, or isopropyl alcohol. There are two stable isotopes, 63Cu and 65Cu, along with a couple of dozen radioisotopes. The vast majority of radioisotopes have half lives on the order of minutes or less; the longest lived, 64Cu, has a half life of 12.7 hours, with two decay modes, leading to two separate products.

It is insoluble in water (in which it is stored—see Figure 6a), is very soluble in carbon disulfide, and bursts into flame in air. As a solid, as a liquid, as a gas, and in solution, white phosphorus exists as P 4 molecules with four phosphorus atoms at the corners of a regular tetrahedron, as illustrated in Figure 6b.
Calcium Sulfate | Encyclopedia
Insoluble in water and most organic solvents The physical properties of the three forms of calcium sulfate differ somewhat from each other, but their chemical properties are essentially the same. Anhydrous calcium sulfate and calcium hemihydrate are fine white odorless powders or crystalline solids, while the dihydrate may occur either as a powder or as white lumps.
