Introduction A complex ion consists of a metal ion with Lewis bases attached to it. These Lewis bases form strong coordinate covalent bonds with the central complex ion in which both electrons of the bond are donated by the Lewis base. The Lewis bases that form this complex are referred to as ligands and they are typically either neutral molecules or anions. Polydentate ligands have multiple lone pairs of electrons that enable them to bond multiple atoms to the central metal atom. The stability

The topic is Distorting Our Likes and Dislikes. The appropriate definition is post decision dissonance which is “dissonance aroused after making a decision‚ typically reduced by enhancing the attractiveness of the chosen alternative and devaluating the rejected alternatives.” (Aronson‚ E.‚ Wilson‚ T. and Akert‚ S.

Structures‚ Biosynthesis and Biofunctions of Iron-sulfer proteins Yiming Chen‚ Brown University‚ May 11th‚ 2011 I. Introduction Iron-sulfur proteins are the proteins which contain iron-sulfur clusters‚ like sulfide-linked di-‚ tri-‚ and tetrairon centers with various oxidative states 1. An excess of 120 distinct types of enzymes and proteins are known to contain Fe-S clusters2. Iron-sulfur proteins are known for the role of the oxidation-reduction reactions of mitochondrial electron transportation

How did the iron curtain start? Why was it protected by the warsaw pact? Where was the iron curtain at? The term first became popular by Winston Churchill when he used it in a speech in March of 1946. This speech was also considered to be the “announcement” of the start of the Cold War(History.com). At this time the term was first used to refer to the actual metal barrier that cut the continent in two‚ but it soon became a reference to the ideological barrier also. The iron curtain is a term used
