AuAl 2 is the most thermally stable species of the Au–Al intermetallic compounds, with a melting point of 1060 °C (see phase diagram), which is similar to the melting point of pure gold. AuAl 2 can react with Au, therefore is often replaced by Au 2 Al, a tan-colored substance, which forms at composition of 93% of Au and 7% of Al by mass. It ...
The Au−Xe bond length is 274 pm (2.74 Å). [2] [3] Tetraxenonogold(II) is unusual in that it is a coordination complex of xenon, which is weakly basic. It is also unusual in that it contains gold in the +2 oxidation state. It can be produced by reduction of AuF 3 by xenon in the presence of fluoroantimonic acid.
The #6-32 UNC screw has a thread pitch of 1/32 in (0.031250 inches (0.7938 mm)).. The #6-32 UNC is a UTS screw specifying a major thread diameter of #6 which is defined as 0.1380 inches (3.51 mm); and 32 tpi (threads per inch) which equates to a thread pitch of 0.031250 inches (0.7938 mm).
Despite being a compound of two metals, CsAu lacks metallic properties since it is a salt with localized charges; it instead behaves as a semiconductor with band gap 2.6 eV. [4] The compound hydrolyzes readily, yielding caesium hydroxide, metallic gold, and hydrogen. [3] 2 CsAu + 2 H 2 O → 2 CsOH + 2 Au + H 2

By Dan Catchpole. SEATTLE - CEO Kelly Ortberg took over at Boeing knowing that the company was in trouble. Those troubles added up to an $11.8 billion loss last year, the company reported on Tuesday.
Gold(II) sulfate is the chemical compound with the formula AuSO 4 or more correctly Au 2 (SO 4) 2. This compound was previously thought to be a mixed-valent compound as Au I Au III (SO 4) 2. But later, it was shown that it contained the diatomic cation, Au 4+ 2 which made it the first simple inorganic gold(II
Ohio State (13-2), which has won over No. 9 Tennessee, No. 1 Oregon, and No. 5 Texas during its CFP championship run, is seeking its first national championship since 2014.
