In the history of chemistry, there was a chemist who left the world with intense debate about his the merits and demerits. He is the world-famous German physical chemist, inventor of ammonia Fritz Haber. The people who praised Haber say he was an angel, bring joy and harvest to mankind. The people whom cursed him say that he is a devil, a disaster for humanity, suffering and death. Haber was born in Silesia Breslau (now Wroclaw, Poland) on December 9, 1868, his father was a knowledgeable and good Jewish businessman, and this family environment impacted his fate with chemistry. Haber was very talented and mastered plenty of chemistry knowledge at a young age. He went to Berlin, Heidelberg, and Zurich to study. After graduating from the University of Jena, Haber was engaged in organic chemistry research. His paper once caused a sensation in the chemical industry. When Haber was 19, he was granted in Germany, the Royal Institute of Technology Ph.D., and in 1896 at Karlsruhe University as a lecturer. 1901 Haber married Clara Immerwahr and in 1906, Haber became professor of physical chemistry and electrochemistry.
In able to produce ammonia, nitrogen and hydrogen gas mixture composed together under high temperature, high pressure conditions and the role of catalyst. In the spirit of perseverance, through continuous experiments and calculations, Haber finally achieved encouraging results in 1909. When the temperature is 600 degree Celsius, under the conditions of 200 atmospheric pressure and osmium catalyst, the yield was approximately 8% of ammonia. 8% conversion rate is not considered high; it will obviously affect economic production. Haber known ammonia production cannot attain high conversion rate like sulfuric acid. Haber cons...

...s used to make fertilizer. Many household cleaning products also contain ammonia because it gives the surface a fine and fair shine. Ammonia synthesis was used to produce explosives in World War 1 and it was later used on the development of the deadly poison gas. Therefore there were many skeptical controversies about his winning of the Nobel awards because of the mass number of casualties due to chemical weapons.
Haber's vision of ammonia was finally achieved in 1913. The ammonia production method not only opens the way to get fixed nitrogen, more importantly, this production process has a significant impact on the entire development of the chemical technology process. The decision to grant the Nobel Prize in Chemistry to Haber is correct despite his achievement in the production of ammonia and the impact of his research which pushed the chemical theory forward.

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 .
Mary Maynard Daly was born on April 16, 1921 in Corona, Queens and was the daughter of the well-educated Ivan C. Daly and Helen Daly. The Daly’s were well cultured and educated but could not wholly peruse their dreams because of financial complications so Mary Daily took her parents endeavor and turned it into her personal incentive. In addition, Daly’s grandparents contributed a vast role in her road to triumph, by laying down the groundwork of chemistry when she was younger. When Daly visited her grandparents who lived in Washington D.C she was able to read bout scientist and their accomplishments in her grandfather’s diverse and informative library. During her readings at her grandparents’ house, Daly found her science muse, a chemist named Paul De Kruif who made her decision to pursue chemistry as a career assured. Later on Daly married Vincent Clark, in 1961 and decided to move to Florida and unfortunately Daly died in 2003 and the cause of her death was unknown.
This person joined the Nazi party and worked his way up to the top. People called him cruel. Even Hitler said that he was one of the most cold hearted SS officer he had ever met. This person was no other than Reinhard Heydrich.

Another discovery Ehrlich made was of a dye called trypan red. Trypan red helped destroy cells that caused sleeping sickness. His research of antibodies and understanding how the antibodies attack harmful substances that enter the body has made him the "founder" of modern chemotherapy.
The family member that Oliver Sacks seemingly related to the most was his uncle Dave (nicknamed Uncle Tungsten). Because of Uncle Dave, Oliver gains his initial interest in chemistry and acquires many-detailed information that gets described in the book, thus introducing the educational value of chemistry in the book. This book also goes into great detail in the experiments performed from Oliver Sack’s experience, explaining the functions associated with each procedure and why they are essential. And aside from the factual information, there is noticeably great detail about the history of chemistry concerning what different individuals contributed to chemistry.
Since a boy, Frankenstein’s passion is to explore science and that which cannot be seen or understood in the field. He spent the later part of his childhood reading the works of commonly outdated scientists whose lofty goals included fantastic, imaginative desires to “penetrate the secrets of nature” (Vol. 1, Ch. 2). While he was told that these authors predated more real and practical scientists, he became intrigued by their ambitions, and devoted himself to succeeding where they had failed. When Victor is criticized at college for his previous studies in obsolete research, he takes after one of his professors, M. Waldman, in studying chemistry. In a lecture, Waldman tells of ancient teachers in chemistry who promised miracles and sought after “unlimited powers” (Vol. 1...
In the mid 1800’s Fritz Haber was born in Breslau Germany as a jew. Their he married his wife, Clara. In the early 1900’s he became a professor, and then worked at a corporation called BASF. At BASF Mr. Haber pondered the future of Germany. The future was so prevalent in his mind because Germany was facing a problem. Germany’s problem was that they only had enough food to feed 40% of the population. Mr. Haber being a patriot and man of science was eager to help his country. Mr. Haber knew that the atmosphere is 78% nitrogen, and nitrogen is needed to produces crops. He needed to manipulate nitrogen in the air to a usable product for cultivating land. He created a catalyst that could heat and compress nitrogen and hydrogen to create ammonia, or fertilizer. The result of his invention was
This chemistry book report is focus on a book called “Napoleon's buttons: How 17 molecules changed history” by Penny Le Couteur and Jay Burreson. The publisher of this book is Tarcher Putnam, the book was published in Canada on 2003 with 17 chapters (hey the number match the title of the book!) and a total of 378 pages. The genre of this book is nonfiction. “Napoleon's Buttons” contain a fascinating story of seventeen groups of molecules that have greatly changed the course of history and continuing affect the world we live in today. It also reveal the astonishing chemical connection among some unrelated events, for example: Chemistry caused New Amsterdamers to be renamed New Yorkers and one little accident of detonating cotton apron in a minor housekeeping mishap lead to the development of modern explosives and the founding of the movie industry.
Alfred Nobel impacted the citizens of the United States because he invented an explosive called dynamite, and the Nobel Peace Prize. He invented and manufactured it to increase the killing power, and made was more dramatic. The Nobel Peace Prize was made to award the person in the preceding year, has done the most, or the best work between nations. The Nobel Prize was made to award people who impacted the United States, and the dynamite was one impact on the world. In conclusion Alfred Nobel impacted the world with an explosive that changed wars, and the Nobel Prize to award people who do good things for the world.

These are some of the many properties reasons and qualifications for us using sodium in our everyday lives. These are the reasons why sodium is used all around the world to this very day and is also why we use so much of it. Ammonia has an important role in the formation of salt crystallizations which is why it is mentioned in the above paragraph and which so will be used in the experiment that is going to take place to test the importance of ammonia in salt crystallization and to see exactly how the ammonia is going to affect the salt in the end result.
