Experiment Title: A Separation and Purification Scheme. Kunal Patel T.A: Justin Maxwell 2460-008 November 8, 2016 Introduction: This experiments main purpose was to separate and purify the components of the unknown substance given. The unknown had been allotted in the lab according to the initials of the last name. The three unknown components were 50% o-toluic acid, 40% fluorene and 1,4-dibromobenzene. This lab was essential because each student had to create the lab protocol for the lab

The laboratory exercise that I performed was to simulate the physical and chemical weathering of rock. During this exercise, the materials that I used were white vinegar, a piece of blue chalk broken into 5 equal parts, water, plastic bag, 5 small cups, and a measuring cup. The purpose of this exercise was to determine which factors were physical weathering and which were chemical weather. I would also be able to determine what factors affect the rate of weathering. My hypothesis: The white

Every act or omission by a healthcare professional can have dire results on his patient. Medical negligence is mainly the application of the general law of negligence on to the medical profession. The elements of negligence are the duty of care, breach of that duty of care, causation and actual damage to that person or property1. The same principles applies in medical negligence, however specific to this area, more attention is paid in the areas of causation and the level of standard of care that

It was just a regular day at the science lab in Australia. I was working on a pill that will stop bad gas, Caiden (another scientist) was trying to figure out why animals have so much hair, and Caleb was taking a nap. Caiden was examining the hair of a kangaroo and a giraffe. I just finished creating my mixture to make the pill and that 's when it happened; Caleb farted so loud it made the lab shake. My mixture was shaking back and forth, and “CRASH” my mixture fell on the two animals and a huge

Dear Dr. Hein, I wish to apply my skills and knowledge in synthetic organic chemistry to the Research Assistant position in the Hein Lab at the University of British Columbia for the Summer of 2023. My career goal is to conduct exploratory research while educating and instilling passion in young individuals as a research professor of organic chemistry. Presently, I am completing my Bachelor of Science in Chemistry, Life Science, and Environmental Science at the University of British Columbia. I

Living As A Fiery Redhead Have you ever wondered why people have redhair? Or what makes someone’s hair red? That’s the part that can be tricky to understand, even to someone who was born with redhair. Redhair is a distinct feature that often stands out in a crowd. People with red hair, commonly referred to as redheads or gingers, have a unique and recognizable personality that impacts their lives in many different ways. There are many things associated with being a redhead. Such as, certain traits

Specific Purpose: By the end of my speech, the audience will know about the problem of conducting experiments on animals and the ethical issue of the cruel treatment of animals by the researchers. While the problem of conducting experiments on animals draws attention of the society, the speech would present the limitation of animal experiments and outline the alternatives. Central Idea: 1. Conducting experiments on animals has become one of crucial ethical issues of the modern society and it has

Comparison of Laboratory Protocols of Classroom Settings to those Practiced on a Commercial Setting Brittany Weishuhn 24 October, 2015 Texas A&M University at Galveston, Galveston, Texas INTRODUCTION The purpose of the report is to compare and contrast classroom laboratory procedures, safety, and storage to those practiced on a commercial level as seen at the Texas City Oil Refineries. COMPARISON OF STORING CHEMICALS Storage of Chemicals on a Commercial level as seen at the Texas City Refineries

Identification, Properties, and Synthesis of an Unknown Ionic Compound (Magnesium Chloride) Kaelyn O’Neill Chemistry 1010 Laboratory, Section 03 Instructor: Khushi Patel October 12, 2014 My signature indicates that this document represents my own work. Outside of shared data, the information, thoughts, and ideas are my own, except as indicated in the references. I have submitted an electronic copy through Blackboard to be scanned by TurnItIn.com.

This lab consists of four main parts, all relating to the main purpose of observing and measuring the effects that changes in temperature, pH, and enzyme concentration can have on reaction rates of an enzyme catalyzed reaction, as mentioned previously. In the first part we observe a normal catalase reaction and rate its reaction rate. In the second part we learned which tissues, of the ones tested, contained catalase. In the third part we saw how temperature can leave an effect on catalase activity

Tanay Bapna –The focus of our 4th quarter in 9th Grade Science was chemistry. We spent a lot of time in the lab seeing first hand how chemical reactions occur, and practiced writing descriptive designs for the labs we did. Our lab and projects included a melting point lab, flame test lab, an atomic theory essay, a carbon dioxide lab, a pennies to gold lab, and a hydrogen lab. Next year students in 10th grade at HIS will study biology. Tanay is an excellent chemistry student. In the lab he was

family or friends, but for some, love is the most important thing on earth, which in return, if their fragile heart is broken, may end badly for any parties involved. This perfectly explains the speaker in Robert Browning’s dramatic monologue, “The Laboratory.” Browning based this wonderful poem on a true historical individual who goes by the name of, Marie Madeleine Marguerite D'Aubray, marquise de Brinvilliers, who had killed her two brothers and her father by using poison. (Shmoop). As the dramatic

Several protocols were used throughout the extent of the experimentation, such as during the development and purification of the organic complex. In the developmental phase of the organic complex, traditional methods of cycloaddition reactions were studied and analyzed to provide a basic understanding of a possible design for a practical reaction with cyclooctyne, The characteristics of Click Chemistry reactions were also studied and aided the experimental design of this project. The methodology

emergency departments have somewhat been affected by timely reporting of laboratory tests results. Hence, timely laboratory TAT is important from a medical and also a commercial point of view. A recent analysis of lab TAT indicated that review of this time interval has significantly helped in determining the cause of a lag, which is then followed by the improvement in TAT. This issue is tremendously important and laboratories cannot stress enough on its relevance. Appropriate and rapid clinical decisions

Wondering why animals act a certain way is possibly a question that can never be answered correctly. Asking why animals act a certain way in an environment though, now that may be a question that can be answered! It has become a proven fact that animals act differently in every different environment and around every different animal or person. For instance, take a lion that is being taken from his home environment to a zoo. Of course, that lion is going to act up before he gets used to his environment

Before proceeding with the experiment, the theoretical yield was calculated to be 0.945 g. After preparation of the product, the theoretical yield was used to determine the percent yield, which was found to be 79%. Due to this reasonable yield, it was concluded that the synthesis of methyl orange had been successful. Data Table 1 gives the results and observations that were recorded throughout the preparation of methyl orange. According to literature, methyl orange is an azo dye that forms orange

Hi, im Bean the ghost, i was abandoned by my parents when i was 8 months old. I was left at these old peoples house that i really hate. I have lived in Michigan for my whole life and now im 17 years old and the only friend i have is a jelly bean jar, his name is Jammy. He sometimes gives me jelly beans and it reminds me of eating little kids. Anyways im here to tell you about how my life changed by a little boy named Flib. I was in my room on a cold, wet, happy day when I saw one of those cars
