experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few. Molecular geometry is associated with the specific orientation of bonding atoms. A careful analysis of electron distributions in orbitals will usually

Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

RACE Definitions/Concepts Racial Formation: idea of how race is created. Race: socially constructed categorization process that describes phenotype‚ not genotype. Ethnicity: nationality/origin. Whiteness: ideology tied to social status‚ provides privilege for those labeled white; process by which non-white “other” created for benefit of whites. Racism: about structural advantages/disadvantages placed on people based on perceptions of their race. Can be individual or institutional. Covert: not hiring

Concepts – Chapter 10 Hershey and Chase experiments (10.1) Hershey and Change mixed radioactively labeled phages with bacteria‚ they agitated the cultures in a blender to separate the phages outside of the bacteria‚ they centrifuged the mixture so that the bacteria formed a pellet‚ and finally‚ they measured the radioactivity in the pellet and liquid Phage replication (10.1) A phage attaches itself to a bacteria cell‚ the phage injects its DNA into the bacterium‚ the phage DNA

COORDINATION CHEMISTRY Factors t hat affect solubility: Common ion: decrease in solubility Complex ion: increase in solubility How does complex ion formation increase solubility? Consider the complex ion formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water
