Poison Gas There were many small things that eventually caused World War I. The spark that started the First World War was the assassination of Archduke Franz Ferdinand‚ heir to the Austro-Hungarian throne‚ in Sarajevo on 28 June 1914 (Duffy). The killing was blamed on the Serbians‚ making the Austrian-Hungarians declare war on them. Russia was bound to a treaty with Serbia so it made Russia have to step in. Because Russia stepped in‚ more and more countries had to get involved due to

Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

3.7 Nuclear Independent Chemical Shift Analysis The Nuclear Independent Chemical Shift is measured as magnetic shielding of a molecule have been calculated at the B3LYP/6-31G theory level. Aromaticities are represented by negative NICS Values and antiaromaticity is represented by positive NICS Values. The large negative NICS Values of the title compound represent stronger aromaticity [29-35].Our present investigation of the density functional calculations of doped fullerene with glycine shows several

Objective: The goal of the experiment was to use UV/VIS spectroscopy to collect data to quantify acetaminophen‚ aspirin‚ and caffeine from a migraine tablet where there is heavy spectral interference using Target Factor Analysis1. The migraine tablet has other ingredients in it like FD&C blue #1‚ stearic acid‚ and saccharin. Saccharin is the ingredient thought to have the biggest interference and was used as the experimental basis2. Instruments: UV/VIS spectroscopy was used to analyze the absorption

(1) Answer to Question in lab manual. NO introduction/background etc. 1. What is the retention time for caffeine? Retention time for caffeine : 4.149+4.142+4.152+4.1454 = 4.15 2. What is the retention time for benzoic acid? Retention time for caffeine : 2.651+2.817+2.857+2.9274 = 2.81 3. How are the retention times for caffeine and benzoic acid related to their chemical structure and the nature of the chromatographic

In this lab‚ we extracted spinach pigments‚ and analyzed what colors of light these pigments absorb. By using TLC plate‚ hexane and acetone‚ I separated the pigments of spinach‚ and discovered that the main pigments were green and yellow. This works because with different polarities‚ pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know

corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be
