Copper(II) bromide (Cu Br 2) is a chemical compound that forms an unstable tetrahydrate CuBr 2 ·4H 2 O. It is used in photographic processing as an intensifier and as a brominating agent in organic synthesis .
The copper(I) ion also oxidizes easily in air. It is commonly prepared by the reduction of cupric salts with sulfite in the presence of bromide. [4] For example, the reduction of copper(II) bromide with sulfite yields copper(I) bromide and hydrogen bromide: 2 CuBr 2 + H 2 O + SO 2− 3 → 2 CuBr + SO 2− 4 + 2 HBr
Ball-and-stick model of the complex [Cu(NH 3) 4 (H 2 O) 2] 2+, illustrating the octahedral coordination geometry common for copper(II). Polyols, compounds containing more than one alcohol functional group, generally interact with cupric salts. For example, copper salts are used to test for reducing sugars.
Anthropogenic and natural sources of bromine. The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources. Sinks include exchange of brominated compounds with the stratospheric and troposphere.Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer ...
The Game of Life, also known as Conway's Game of Life or simply Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. [1] It is a zero-player game, [2] [3] meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial ...

For example, Conway's Game of Life has a transition rule = (,,,). [1] We can use this transition rule to create different variants of the Game of Life. For instance, an automaton with R = ( 3 , 4 , 3 , 4 ) {\displaystyle R=(3,4,3,4)} results in an explosive variant of the Game of Life called 3-4 Life, and one of the earliest studied variants of ...
Evolution of an MSM breeder – a puffer that produces Gosper guns, which in turn emit gliders.. In cellular automata such as Conway's Game of Life, a breeder is a pattern that exhibits quadratic growth, by generating multiple copies of a secondary pattern, each of which then generates multiple copies of a tertiary pattern.
