BUSINESS ECONOMICS: ECON 545 Course Project: Part 1 Professor Robert Senn INTRODUCTION Based in recent surveys‚ reports show a trending decline on the rate at which physicians move. Statistically‚ this (may) suggest the economy is preventing or affecting physicians from frequent job changes‚ or retirement. According to survey results‚ the move rate was reported as follows: 18.2% in 2008‚ 15% in

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

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
