Complex Ions Complex ion - ionic species consisting of a metal ion bonded to one or more Lewis bases Coordinate bond - bond formed when one anion/molecule donates a pair of electrons to another ion/molecule to form a covalent bond Ligand - a Lewis base bonded to the central metal ion of a complex ion Common Ligands (Lewis Bases): NH3, H2O, OH-, Cl-, CN- Inner coordination sphere - ligands that are bound directly to a metal via coordinate covalent bonds Counter ions - ions that balance the electrical charges of complex ions in coordination compounds Ex: [Ag(NH 3 ) 2 ] + + Cl - ?> [Ag(NH 3 ) 2 ]Cl Coordination compound - any compound that contains a complex ion Coordination number - identifies the number of electron pairs surrounding a metal ion in a

The Evolution of Psychology Psychology is an ancient art ?psyche? = soul ?logos? = study of a subject And a less ancient scientific discipline early 18th century - ?study of the mind? Multi-disciplinary approaches: Room for chemists, biologists, physiologists, sociologists, anthropologists, evolutionary everythingists, etc. Intellectual parents - philosophy and physiology And Wilheim Wundt, the godfather United all the different questions under one common mystery umbrella 1870 - first lab founded in University of Leipzig The Early Growth Phase Thanks to Wundt, started off on a good science foot. Scientific study of conscious experience: Attention Sensation and perception Reaction time etc.

Alkenes are commonly described as unsaturated hydrocarbons because they have the capacity to react with substances that add to them. Alkanes, on the other hand, are saturated hydrocarbons and are incapable of undergoing addition reactions. 6.1 Hydrogenation of Alkenes The relationship between reactants and products in addition reactions can be illustrated by the hydrogenation of alkenes to yield alkanes. Hydrogenation is the addition of H 2 to a multiple bond, as illustrated in the conversion of ethylene to ethane. The reaction is exothermic and is characterized by a negative sign for ?H?. Indeed, hydrogenation of all alkenes is exothermic. The heat given off is called the heat of hydrogenation and cited without a sign. In other words, heat of hydrogenation = -?H?.
