Inorganic chemistry Essays

In organic and inorganic chemistry, nucleophilic substitution reactions are the most well studied and useful class of reactions. These reactions can occur by a range of mechanisms, the two studied in this lab are the SN1 and SN2 reactions. In a nucleophilic substitution, the nucleophile is a electron rich chemical species which attacks the positive charge of an atom to replace a leaving group. Since nucleophiles donate electrons, they are defined as Lewis bases. The positive or partially positive

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

The Joy of Chemistry is a book about the adventurous and wonderful things that deal with chemistry. The book is written by two chemists named Monty Fetterolf and Cathy Cobb. This book is for anyone that wants to become familiar with chemistry rather it is an adult that wants to refresh their memory or a student that is having trouble with the subject in school. The book is made up of experiments, which can be conducted at home with the few items listed in the checklist in the beginning of the book

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

unstable when present with hydroxyl groups. Finally, R is a space moiety, which can be aryl or alkyl chain. Typically, due to the dual reactivity of organosilane, both alkoxy group (OR\) and non-hydrolysable organic moiety (X), it is used to couple inorganic or organic substrates such as minerals, metals or cellulose and polymeric matrices such as rubber, thermoplastic or thermosets to improve its physical properties. The applications include adhesion promoter, dispersing/hydrophobing agent and crosslinking

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

The fermentation does not require external electron acceptors because the organic contaminant serves as both an electron donor and an electron acceptor. Through a series of internal microorganism-mediated electron transfers, the organic contaminant is converted into harmless compounds known as fermentation products. Examples of fermentation products are acetate, propionate, ethanol, hydrogen and carbon dioxide. Fermentation products can be biodegraded by other species of bacteria, eventually turning

To become a scientist and my strong admiration to utilize my chemistry knowledge, I have decided to pursue graduate studies. With my academic intellect, I want to make a compelling impact on the life of the individuals, as well. An instinctual enjoying towards science and passion towards technology, highly influenced me to be a researcher in the field of chemistry; especially in petroleum chemistry. Since one of the recognized and designated research intensive university among public and private

For the last 5 decades, electronics coupled with organic chemistry has been an area of great research interest, especially in physics and chemistry. Until a few years ago, this topic was thought to have no practical approach and was believed to be just research-oriented. Modification of chemical structures so that they can in a way enhance the properties of these when used for electronic applications- especially as a thin film has gained major impetus. It was always thought that organics would soon

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

The timeline of chemistry has many important discoveries, ideas and experiments that changed people's understanding of the modern science known as chemistry. There are currently 118 elements known by mankind but it has taken a long time to get to where we are today. Over this long period of time many scientists have experimented and discovered things that are correct even today and some discoveries that are not. This assignment is going to be about the main scientists that had vast contributions

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

1.1 Boron History & Overview: Boron is an element of the periodic table belonging to the group 13. It is the only non metal present in its group. Boron has three valence electrons. It is capable of forming covalent bonds between atoms of similar nature to form polyhedral clusters. Boron has 2 stable isotopes in nature. i.e.11B (80.1%) and 10B (19.9%). Boron exists in bound state. Figure1. Elemental form of boron The history of boron is derived from almost 6000 years ago, when boron compounds

General Background: There are many different macromolecules present in nature, the most predominant molecules found in living organisms. In analytical chemistry, indicators are chemicals (reagents) that help identify the composition of an unknown material. In solution analysis, indicators are used to predict the presence of certain organic or inorganic compounds such as sugars, proteins, starches, lipids, or vitamins. There are two types of testing, qualitative

Free radicals, acknowledged in chemistry since the birth of the 20th century, were originally used to describe common compounds in organic and inorganic chemistry, and several chemical definitions for them were suggested. Only in 1954 when the pioneering work of Daniel Gilbert and Rebecca Gersham was published (Gilbert DL (ed.), 1981) were these radicals proposed as important players in biological environments and responsible for destructive processes in the cell. After which, in 1956, Herman Denham

Rate of Reaction Experiment Rate of reaction is a term used to measure the time or speed that the reaction occurs in. A rate of reaction can be effected by different factors, such as the concentration, temperature, whether or not a catalyst is involved, the state that the reactants were in at the time of the experiment and the amount of pressure that was involved in the experiment. If the concentration, temperature and the amount of pressure involved were higher than the rate of reaction would be
