Beryllium hydroxide, Be(OH) 2, is an amphoteric hydroxide, dissolving in both acids and alkalis. Industrially, it is produced as a by-product in the extraction of beryllium metal from the ores beryl and bertrandite. [7] The natural pure beryllium hydroxide is rare (in form of the mineral behoite, orthorhombic) or very rare (clinobehoite ...
Beryllium hydride (systematically named poly[beryllane(2)] and beryllium dihydride) is an inorganic compound with the chemical formula (BeH 2) n (also written ([BeH 2]) n or BeH 2). This alkaline earth hydride is a colourless solid that is insoluble in solvents that do not decompose it.
Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide.
The compound in which a benzene ring is fused to arsole — typically on the carbon atoms 3 and 4 — is known as benzarsole. [3] Cumene (C 9 H 12), an aromatic hydrocarbon used in the production of phenol and acetone. Cummingtonite ((Mg,Fe 2+) 2 (Mg,Fe 2+) 5 Si 8 O 22 (OH) 2), a magnesium-iron silicate hydroxide, first identified in Cummington ...
