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

Chromatography (TLC) and Melting point. Introduction: There are only several compounds and molecules that are essential to the human body. Such molecule like D-glucose which is considers the second central substance in the maintenance and metabolite of human life after water. D-glucose is an important monosaccharide and has being subjected to many years of NMR analyses due to its anomeric properties of αand βusing deuterium1. Both anomers of D-glucose have a similar structure with a molecular formula of C6H12O6

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

Petroleum‚ in one form or another‚ has been used since ancient times‚ and is now important across society‚ including in economy‚ politics and technology. The rise in importance was mostly due to the invention of the internal combustion engine‚ the rise in commercial aviation and the increasing use of plastic. More than 4000 years ago‚ according to Herodotus and Diodorus Siculus‚ asphalt was used in the construction of the walls and towers of Babylon; there were oil pits near Ardericca (near Babylon)

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

My Journal Monday (09.07.2012) We arrived at Bengaluru International Airport around 5.25 pm and we set our watches to Bengaluru time which is 2½ hours later than Malaysian time. After 4 hours in Airasia AK1212‚ we finally reached Bangalore for our conference tomorrow. We stayed in Woodlands Hotel and it is about 1 hour journey from the airport. Our conference will be held in ITC Gardenia‚ the first green hotel in the world which is just across the road from where we stayed. Tuesday (10
