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

Social Welfare Social welfare in the United States has evolved greatly in the past several hundred years. Social welfare began as a voluntary measure and evolved into a government controlled program with many different Characteristics taking place over time bringing us to the program we have today. Many players were involved though out history with different groups and people. I will use the three factors: 1.where social welfare began. 2. Why Social welfare began and 3.some of the major players

The American Promise is a phrase which has been used in all different areas of American life. From 1492‚ when Columbus sailed to the vast and empty land soon to become America‚ to 2017‚ where we are a superpower on a global stage‚ the American Promise has reigned all through history. The question that must be asked is‚ what is the American Promise? I believe the American Promise seeks to convey the ideal of a unified‚ equal‚ and free country that takes the weight of the poor man lifts his burden

EXPERIMENT 2: SYNTHESIS OF ORANGE II (2-NAFTHOL ORANGE OBJECTIVE 1. To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain

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
