AIM Design an experiment to study a thermodynamic property of a chemical substance, a chemical reaction, a physical change or chemical phenomenon. BACKGROUND INFORMATION Standard enthalpy change of solution, ∆Hsolnø, is the enthalpy change when one mole of a substance dissolves in water to form a solution of infinite dilution under standard conditions.1 The standard enthalpy change can either be exothermic or endothermic. An exothermic reaction is a reaction where energy is released as a form of

Aim The aim of the experiments to be carried out is to determine the kinetic parameters, Km and Vmax, of Alkaline Phosphatase. Theory, Principles and Application of Principles Enzymes are a huge varying group of proteins which are needed to carry out essential metabolic functions in cells. Substrate-specific enzymes, like Alkaline Phosphatase, act as catalysts lowering the needed activation energy to convert the substrate to product. Enzymes are made up of amino-acids and amino-groups have side chains

may also serve as the basis for work in many areas outside pure chemistry, such as materials science, medicine and other health-related fields, pharmacology, patent law, business, computation, or environmental science. After general chemistry courses, depending on his or her background, the student makes an intensive core study of some of the major areas of chemistry—organic, physical, inorganic, and analytical chemistry. The chemistry coursework in these degree plans culminates in approximately three

In the subject of chemistry there are many standards, the main six standards include, mass, volume, chemical reactions, chemical changes, and physical changes and the periodic table. Mass is the weight of an object such as “3 pounds”. Volume is the amount of space an object or substance takes up, such as a 5x5x2 box takes up 50 cubic feet. The periodic table is a way to organize all the elements into a sensible organized “table”. These are all important in chemistry because without them you would

Linus Pauling Linus Pauling was a very important scientist who over seven decades of his life made many discoveries in multiple fields of science including: physical, structural, analytical, inorganic, organic chemistry, and biochemistry. He was born in the 20th century and contributed greatly to science field during this time. He is known for “Pauling’s Rules” and other inventions he is responsible for. He would also go on to write his own books detailing some of his work, he made very diverse

that utilizes both physical and life sciences to produce, transport, transform, and use chemicals, materials, and energy. People in this field turn their prowess in chemicals towards energy, medicine, electronics, and materials. My interest in Chemical Engineering stems from the diverse amount of jobs it translates to and also its large influence of Chemistry. I began to become interested in Chemistry my junior year of high school when I decided to take AP Chemistry. Chemistry drew me in because

University of Dhaka gave me undoubted enjoyment and happiness, I want to continue research work and become a researcher in chemistry. I, Dewan Russel Rahman, am applying to the Master of Science (M.S.) degree in the Graduate Program of Department of Chemistry at Central Michigan University (CMU). This, in my view, would be the first step to fulfill my goal of becoming a researcher in chemistry. From my graduate and undergraduate studies I have developed research interests in

I chose the job as a forensic chemist. The forensic chemist help solve crimes by gathering physical evidence and analyzing it in a lab. The types of evidence they find are from fibers, paints, glass, and stains. They use a lot of different technologies like microscopy and gas chromatography. The average salary is from 27,683 to 52,471 dollars a year. Forensic chemists usually work in a laboratory setting and they often go standing for long periods of time with a lot of technical equipment. They

little girl, I have had an interest in the field of chemistry, so when I began my college search I knew I had to look for those colleges who had an outstanding chemistry program. In the midst of my research, I discovered Boston University. Boston University attracted my attention because it had all the qualities I was looking for: a prestigious chemistry program and ethnic diversity within an urban city. Boston University’s prestigious chemistry program involves hands-on interdisciplinary research

By understanding the basics of chemistry, many discoveries and inventions have been made that improve life. In the novel, The Chemy Called Al, Wendy Isdell uses fictional characters, places and events to give readers an understanding of basic chemistry concepts

My constant urge to learn, explore and be a part of the fast growing world by contributing to its development has been instrumental in kindling interest in me for pursuing doctoral study at Tulane University (PhD in Chemistry). I am a graduate student having a MS in Pharmacology and Toxicology (Wright State University, OH) with a 3.3 GPA. I have experience in research, analysis, proofreading, writing skills, and can quickly adapt to meet goals in any environment. I would like to present my past

Dmitri Mendeleev is one of the greatest chemists of all time. Among his accomplishments, Mendeleev created the Periodic Table of Elements and wrote many chemistry textbooks. Some of those textbooks are still studied today. Without Mendeleev, the field of chemistry would not be the same. Additionally, without Mendeleev, chemists might not have discovered the periodic table till much later. The works and discoveries of Dmitri Mendeleev have changed the world. Mendeleev starting impacting others

my studies in chemistry and attend graduate school. I aspire to study chemistry because of its essential contributions to the advancement of nanotechnology and healthcare systems. My involvement in the research lab and my senior thesis provided me with such a rigorous, yet invigorating educational experience that I long to continue in graduate school. I intend to explore my passion for understanding chemistry, biology and human diseases at Temple University. The physical chemistry research area

Biochemistry is a branch of science that involves chemistry and living beings. The chemical processes and reactions that occur within living beings is fundamental part of this branch of science. The Biochemical Society gives a better definition of this field:“Biochemistry is the branch of science that explores the chemical processes within and related to living organisms.” Biochemistry is considered a subdivision of two branches of science: biology and chemistry; the skills and techniques that are used in

complexity of biology inside of a cell and investigating the molecular—seeing beyond the limits of the human senses—has been central to my scientific studies. During my PhD program in biophysics, I intend to understand biological systems through physical and quantitative means not only to elucidate molecular mechanisms but to also engineer biology for new purposes. The ChEM-H CBI Training Program would ground my graduate education in interdisciplinarity and allow me to continue to understand the

Antoine Lavoisier, founder of the oxygen theory of combustion, leader of 18th century chemistry, and published author of “Elementary Treatise of Chemistry”. Born in Paris, France on August 26th, 1743, Antoine Lavoisier was born as the only son into a wealthy bourgeois family. In his young life, he showed an abnormal amount of public concern and studiousness. He was introduce to Collège Mazarins’ studies and sciences, and soon after went to study law. Due to the lacking demands of the students at

What is chemistry anyways? When I first think of chemistry, I imagine explosions, test tubes and clouds of smoke. This may be true, partially anyways, but there is so much more to chemistry. Officially, chemistry is “…a science that describes the physical properties, composition, structure and reactions of matter” [1] but how does this really affect us? Imagine all the possible chemistry reactions that is happening inside our very own bodies right now. One example of this is neuroregeneration treatments

Theoretical chemistry is an insightful mathematical tool to understand experimental facts and provide conceptual directions to experimentalists. The discovery of theoretical concepts came after several experimentations and attempts. Earlier progress of theoretical chemistry was narrowed due to the limitation of computational facility. The growth in the empower of electronic computers and softwares have increased the inability to unfold the problems of vigorous calculations into easier forms and enabled
