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

CHEM 301 LECTURE Unit 1 0 . 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

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.

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative
