Chemistry is a branch of natural science that deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes. (University of Idaho, 2014) Molecules, as small as they seem, is in the food that we eat and present in our daily lives. Today, scientists would likely know about the history of chemistry but not how chemistry has impacted history. Many would not wonder if these molecules go beyond the chemistry concepts that they have learned. For example, would the world have been different if piperine (molecule) present in pepper had not led to the discovery of the United States? The interesting fact is that molecules have and will continue to shape the world today. In this book, the authors explain in detail how 17 specific molecules had a significant impact on the history of the world. On a whole, this book is very intriguing and very suitable for chemistry lovers as well as the general public. This book, ‘Napoleon’s buttons’, is written by Penny Le Couteur and Jay Burreson (2003). The book is divided into 17 organized chapters and is based on three major themes, namely medicine, trade and conquest. Molecules that encouraged the discovery of new trade routes include peppers, nutmeg, and cloves, glucose, silk and nylon, morphine, nicotine, and caffeine, salt and dyes. Molecules which have led to battles and wars include ascorbic acid, cellulose, nitro compounds, molecules of witchcraft and isoprene. Molecules which had an important role in the field of medicine include phenol, wonder drugs, the pill, oleic acid, chlorocarbon compounds and molecules versus malaria. The authors’ evaluation on some history events linked to the molecules were rather shallow.

The pictures engage the reader and allow one to have a clearer visual perspective of what is being discussed. Overall, the flow of the book from chapter to chapter was good and well thought. The chemistry aspects provided in the book was very detailed but there were some information lacking in the historical aspects of the book. The authors’ were also quick to conclude on how certain molecules were the sole factor responsible for the historical events. Although there are flaws in the book, this book is still an interesting read. The book is strongly recommended to the general public as it is able to provide to them a basic general understanding of chemistry and allows them to gain new knowledge and great insights into chemistry.
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.

On April 1, 1855, he received his Bachelor’s Degree. Dmitri decided to keep a low-profile . A year later, on April 23, 1856 he received his Master’s Degree . Mendeleev decided to write a book called The Principles of Chemistry. He published it on August 1, 1861 . It was also presented here in a high school quality paperback edition . The publication was produced from a professional scan of an original edition of the book .

We all know the saying, “Don’t judge a book by it’s cover.” Similarly, every element in the periodic table has its’ own story and its’ own unique meaning. However, the average high schooler simply associates these elements as something used in their chemistry classes. In fact, the elements seen on the periodic table actually have much more to do in our daily lives and in history than most people know. While giving a whole new perspective to the meaning of Chemistry, author Sam Kean successfully recounts the hidden tales through humor and wit in his bestselling novel The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of Elements. Specifically, Chapter 15, “An Element of Madness,” addresses the lives of several “mad scientists” associated with selenium, manganese, palladium, barium, and roentgenium that ultimately led to their downfall.

From an early age Pauling served as an example of success for his peers, often offering as a teacher to recently taken classes while he was in school (Simoni, 2003). To give a perspective into the accomplishments of Pauling’s career, he is currently the sole person to be given two Nobel Prizes; the Nobel Prize for Chemistry (1954) and the Nobel Prize for Peace (1962). Pauling published a General Chemistry book that has been used by various programs...
It is apparent that, during certain areas of history, the atomic models repetitively questioned as new material became available in the study of that field. Specific concepts begin to elevate themselves above others and become dominant as they begin being experimented on. Judging by the the literature on the development of the atomic model, the first speculations began around the ancient Greek and Roman times.
Chemistry has had a colossal impact on the advancement of technology throughout the world. Every electronic item can acknowledge chemistry for its creation. A main example that everyone knows of would be the television. Without chemistry, there would be no technology; and without technology, we would not be where we are today.
The development of quantum mechanics in the 1920's and 1930's has revolutionized our understanding of the chemical bond. It has allowed chemists to advance from the simple picture that covalent and ionic bonding affords to a more complex model based on molecular orbital theory.
Not knowing how to calculate the molecular formulas, and not even knowing what molecular formulas are for that matter, proved to be a challenging obstacle for Lavoisier to overcome. Once it was proved that compound atoms had fixed and definite compositions, the first molecular formulas emerged. Oddly, it was John Dalton, a physicist, who discovered the first molecular formulas (Salzberg, 209). Dalton did this by calculating atomic weights through selective interatomic repulsions, and from these repulsions he derived the first molecular formulas. Although it is odd that a physicist derived the formulas used in chemistry, this shows how empirical and molecular formulas have always been necessary in all the
Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
In this analytic research paper, the famous Nobel Prize Winner, Linus Pauling, will be the center of attention through the exploration of several aspects in his life. The prelude of this paper will be a brief historical perspective of Pauling’s upbringing, schooling, and academia. Proceeding is an overview of key individuals who impacted Pauling’s life and journey to his achievements. After seeing the individuals who impacted Pauling; his individual awards and Nobel Prize achievements will be analyzed and showcase their importance towards society. Once we establish his achievements the focus will transfer to certain aspects of contributions Pauling made towards Chemistry and other sciences. Concluding this analytic paper will be any additional
