Chlorine

and that only one peak is given off for enantiomers because they give of the same magnetic resonance. In the reaction below the mechanism starts with a nucleophilic attack from the alcohol, in this case sec-phenethylalcohol, to the PCl3 causing a chlorine atom to leave. The nitrogen from dimethylaniline grabs the hydrogen from the alcohol that’s attached to the phosphate and the electrons from the O-H are transferred to oxygen. Then another molecule of the alcohol attacks the phosphate one again…

if he was exposed to such gases and he would simply die in agony. Germany was the first country to use chlorine gas as an offensive weapon during the battle of Ypres on April 22nd, 1915. There were about 30,000 men involved in the battle and 6000 were killed. The gases made it easy for Germany during their offense and were successful until a Canadian medical officer recognized the gas as chlorine and came up with an antidote. This had a drastic impact because war was no longer fighting in an…

swimming caps and goggles in a pool? Swim caps are used mainly to keep the swimmers hair dry and protected; it also helps protect the hair from the chlorine in the water. Wearing a swim cap can reduce long strands of hair floating in the pool resulting in the hair getting stuck in swimming pool equipment. Swimming goggles protect the eyes from chlorine and if there are any bacteria in the water, it will protect your eye from getting an eye infection such as pink eye. 5. Life guards are present…

My Disney World Experience There is many reasons why my Disney World experience was one of my favorites. The way to Disney was a beautiful ride. The clean smelling airplane and relaxing comfy seats was amazing for my first plane ride. Looking out the window, all I could see was beautiful airy clouds below us and all the people looking like ants when we were about to land. The annoying baby was on my airplane flight. This high pitched cry pierced through my eardrum like if you turn your…

New Technologies A big chemical weapon was used with chemical gases. The chlorine and mustard gases would burn, blind, and kill enemies or anyone who happened to be exposed. Tanks used as well at this time. Tanks could cross onto treacherous territory, and over barbed wire fences of the enemy's land. The most used WW1 weapon was the automatic gun. Automatic guns made it easier for the soldiers to spend less time reloading and more valuable time shooting at the enemies. Machine guns as well as…

1. The Karo syrup experiment started with our dialysis tubing bag with Karo syrup in the bag and the initial weight was 11.09 ounces. We left in a beaker of tap water for 45 minutes and the final weight was 17.98 ounces. The dialysis had a semipermeable membrane and the water soaked through the bag of the syrup. This created a solution of water and syrup 2. The plant takes up water by osmosis and starts to swell. The cell wall prevents it from bursting. Animal cells don’t have a cell wall so…

Silver ions in water purification systems carry oxygen that oxidizes and kills microbes. Silver-copper ions can even replace corrosive chlorine to sanitize pools and tanks. The antimicrobial properties of silver that make it useful to medicine and water purification are also applied in food and hygiene, meaning that silver coatings are applied to food packages and refrigerators. Many new…

Ionic and Covalent bonds are the two different types of bonds that hold atoms together, each having their own characteristics. The distance and charge determines the type of bond the molecules have. These bonds occur because atoms strive to obtain the ideal valence of 8. Some atoms need to gain or lose electrons in order to achieve the ideal valence. In a covalent bond, the electrons are being pulled by two atoms that are both nonmetals. In other words, the two atoms are sharing electrons, but…
