Kolbe-Schmitt Reaction Kira Wall (CHE433) 12-3-14 The Kolbe-Schmitt reaction is named after Hermann Kolbe and Rudolf Schmitt. Schmitt published his research in the Journal fur Pracktische Chemie in 1885 while Kolbe published his research in the Annalen der Chemie und Pharmacie in 1860. The reaction adds a carboxyl group onto the benzene ring of a phenol. The process uses a base carbon dioxide and acid work-up. The original reaction done by Kolbe involved the formation of sodium phenoxide

Most people need to have a chance of privilege to be introduce them to something that would change their life. Knowing someone or having a friend can create an opportunity to better a circumstance is luck and Michael was definitely one of the luckier ones. “ I never called it physics I always called it The PHY because abbreviations and nicknames make everything sound cooler. My interest in physics was immediate. The first thing we talked about was Supreme Scream at Six Flags. Uptown knew that

The Uncertainty principle In 1927, Werner Heisenberg was working at Bohr’s research institute in Copenhagen, Denmark. Neil Bohr and Heisenberg were working closely together on theoretical investigations of quantum theory and nature of physics. Heisenberg was left back at the centre alone when Bohr was away skiing. At this point, Heisenberg realized the limits of physics and physical reality. He realized that it in the act of observing, the observer somehow, manages to alter the reality. This observation

register, then going towards the kitchen door. There is another set of footprints starting by seat A going directly to the kitchen door. The cash register is open, and money is shown coming out. On the lunch counter, in front of seat A, there is a served plate with food on it, and a check paper by its left. To the right, there’s an empty seat without a label. Around the lunch counter are three seats, B, C, and D. All of them

Aesop’s Fables in The Modern World Aesop is the originator of this genre (fables); the Greek people chose the name and created a several legends about Aesop. In Norton Anthology of Western Literature book it says about him, “He had supposedly been a slave and was known for his ugliness and outspokenness. But there is no reason to believe that this has any historical accuracy. The stories about Aesop gave the Greeks and Romans a way of talking about the fables.” He gives a new way to represent ancient

2. Literature Review 2.1 Theoretical Background 2.1.1 The Earth and its Atmosphere In the early twentieth century, a young German scientist named Alfred Wegener, His theory was motivated by the observation that the continents, particularly South America and Africa, seemed to be pieces of a global jig-saw puzzle that had somehow been pulled apart (Asrat, 2006). He reasoned that all land masses were once connected in a gigantic supercontinent he named "Pangaea". The northern part of Pangea is commonly

CHAPTER I THE PROBLEM AND ITS BACKGROUND Introduction Recent earthquakes, particularly the magnitude 6.2 Earthquake in Davao on February 16, 2013, the 5.7 Earthquake in Southern Mindanao on June 1, 2013 and the deadliest earthquake in the Philippines for the past 23 years, the magnitude 7.2 Earthquake in Bohol on October 15, 2013, have caused significant loss of life and severe damage to property. Many aseismic construction designs and technologies have been developed over the years in attempts

The theory of plate tectonics was formulated in the 1960’s, to provide a realistic and complete idea of the processes that produce the Earth’s surface. These plates make up the Earth’s strong outer layer, the lithosphere. “This layer is about 100km thick, which includes the crust and the uppermost part of the mantle.” (Rafferty, 2010) Before the late 1960’s, geologists held the perspective that all the continents and ocean basins were in fixed positions. However this view was quickly dismissed, as

How the Science of earthquakes was started in North America after the California Earthquake of 1906 The California earthquake of April 18, 1906 is one of the most significant earth quakes of all time. The 7.9 magnitude earthquake ruptured the northernmost 477 kilometers of the San Andreas Fault from the northwest of San Juan Bautista to the triple Junction of Cape Mendocino. The earthquake caused severe damage with reports indicating that it caused more than 3,000 deaths and destroyed more than 28

The Tohoku Earthquake was the most powerful earthquake recorded to have hit Japan. The earthquake was a magnitude 9.0 off the coasts of Japan that occurred at 2:46pm on Friday 11 March 2011, which triggered a powerful tsunami that reached the height up to 10.4 meters. A Japanese National Police Agency reported 15,889 deaths, 6,152 injured, and 2,601 people missing, 127,290 buildings totally collapse, 272,788 buildings half collapse, and another 747,989 buildings partially damaged. The Tohoku earthquake

Aerial volcano lies at the convergent plate boundary between an oceanic and continental plate. It is believed to have been formed through the process of subduction. When the two plates converge, the denser and thinner oceanic plate gets bent, or subducted, beneath the lighter and thicker continental plate. The magma rises, becoming lava when it reaches the Earth’s surface. When the lava cools, it forms rock. Over time, after several eruptions in which magma explodes to the surface when pressure in

Chemistry Exploration Topic: determining the activation energy of a chemical reaction Research Question: What effect does temperature of the chemical reaction have on the activation energy ? ICT: Microsoft Word Autograph Microsoft Excel Introduction This experiment is designed to help in estimating the activation energy of the rate-limiting step in the acid catalyzed reaction of acetone with iodine. This is achieved by measuring the reaction rates at different reaction temperatures over

Speech More than 100,000 tons of gum is being consumed every year by people, and most of those people are students. If you ask anyone if they like gum they will most likely say yes and that is probably because in the modern world, we have incredibly diverse flavors of gum. People chew a lot of gum, but is it actually good? Or bad? Gum actually has a lot of benefits and I am only going to mention multiple out of many. FIrstly gum helps students stay focused in class and outside of class. It’s

subduction zone created by the intersection of these two plates sits roughly 100 km south of Tokyo virtually bisecting Sagami Bay. Movements associated with these two tectonic plates triggered the 8.2 magnitude approximate Genroku Earthquake of 1703 and the 7.9 magnitude approximate Great Kantō Earthquake of 1923. Recent scholarship suggests that Tokyo is vulnerable to earthquakes triggered by the movement of yet another tectonic plate or “dislodged plate fragment” located directly beneath the Kantō Plain

1976 Tangshan Earthquake Introduction: At 03:42 AM on Wednesday July 28 1976, it was believed that the largest earthquake had occurred near the Tangshan (a large industrial prefecture-level city in northeastern China with approximately 1 million or more residents) in Hebei with a magnitude of 7.8. The earthquake struck at a very late mid-night (03:42 AM) where more than a million people laid sleeping and not evacuated. The entire earthquake was claimed to last for approximately 14 to 16 seconds

does Aerial Volcano form? Aerial Island is located along a convergent plate boundary between an oceanic plate and a continental plate. When a oceanic plate converges with a continental plate, the denser oceanic plate would subduct under the less dense continental plate At the subduction zone, the tip of the solid mantle material melts and form magma Pressure causes the magma to rise through any cracks in the continental plate Rising magma builds up pressure in the magma chamber The build-up of

Amoxicillin tubes showed growth in all 9 tubes and the control tube. Thus, MIC could not be determined for Amoxicillin. After the incubation period of the six plates prepared from using the clear tubes (Vancomycin), the results were obtained as below, Plate 1 Plate 2 Plate 3 (100 ug/ml) (50 ug/ml) (25

Natural Disasters A disaster is a time-limited complex emergency situation with acute onset that affects a significant number of people and may be of natural, technological or human causes (Kar 2007, Bowman 2011,Briere 2000, Clettenberg 2011). The world has experienced several natural disasters in recent years, affecting millions of people including children – earthquakes in Haiti, China, Pakistan and Iran, tsunami in Japan and Indonesia, hurricane in the United States and cyclones and super typhoon

ash, mud, toxic gases and lava. Mt Saint Helens is one of many active volcanos in the Cascade Mountain Range that runs along the Pacific Coast of the United States of America, a part of the Pacific Ring of Fire, named due to the many active tectonic plates in the region. The blast devastated an area of 20 square km. Within 10km of the summit, were there had previously been dense forest, no trees remained, beyond this area all trees were blown down. A further 600km2 was covered in ash and debris. Mt
