The following exergonic equilibrium gives rise to the triiodide ion: . I 2 + I − ⇌ I − 3. In this reaction, iodide is viewed as a Lewis base, and the iodine is a Lewis acid.The process is analogous to the reaction of S 8 with sodium sulfide (which forms polysulfides) except that the higher polyiodides have branched structures.
The polyiodides are a class of polyhalogen anions composed entirely of iodine atoms. [1] [2] The most common member is the triiodide ion, I −3.Other known larger polyiodides include [I 4] 2−, [I 5] −, [I 6] 2−, [I 7] −, [I 8] 2−, [I 9] −, [I 10] 2−, [I 10] 4−, [I 11] 3−, [I 12] 2−, [I 13] 3−, [I 14] 4-, [I 16] 2−, [I 22] 4−, [I 26] 3−, [I 26] 4−, [I 28] 4− and ...
Clarkdale is the codename for Intel's first-generation Core i5, i3 and Pentium dual-core desktop processors. [1] It is closely related to the mobile Arrandale processor; both use dual-core dies based on the 32 nm Westmere microarchitecture and have integrated Graphics, PCI Express and DMI links built-in.
Core reengineered P6-based microarchitecture used in Intel Core 2 and Xeon microprocessors, built on a 65 nm process, supporting x86-64 level SSE instruction and macro-op fusion and enhanced micro-op fusion with a wider front end and decoder, larger out-of-order core and renamed register, support loop stream detector and large shadow register file.
Arrandale is the code name for a family of mobile Intel processors, sold as mobile Intel Core i3, i5 and i7 as well as Celeron and Pentium. [1] [2] It is closely related to the desktop Clarkdale processor; both use dual-core dies based on the Westmere 32 nm die shrink of the Nehalem microarchitecture, and have integrated Graphics as well as PCI Express and DMI links.
However, the precise composition/structure of these chains, including the balance between molecular iodine and various iodide anions, continues to be debated and investigated, with a 2022 article suggesting that they might alternate. [9] The triiodide anion instantly produces an intense blue-black colour upon contact with starch.
President-elect Trump shared an image of first lady Jill Biden when trying to sell his perfume Sunday. “Here are my new Trump Perfumes & Colognes! I call them Fight, Fight, Fight, because they ...
Before the Coffee Lake architecture, most Xeon and all desktop and mobile Core i3 and i7 supported hyper-threading while only dual-core mobile i5's supported it. Post Coffee Lake, increased core counts meant hyper-threading is not needed for Core i3, as it then replaced the i5 with four physical cores on the desktop platform. Core i7, on the ...
