Chemistry Lab: Haber’s Process (A Computer Simulation) Cherno Okafor Mr. Huang SCH4U7 October 8th‚ 2012 Introduction The Haber process is the process by which ammonia (NH3) is produced. The equation for this reaction is... The symbol shown in the middle means it is a reversible reaction so the product can decompose back into the reactants. Therefore‚ optimum conditions must be selected to get the greatest yield. When the forward and backward reactions are the same‚ it is said

is the duty of scientists in wartime‚ to do everything in their power to help the country. Fritz Haber‚ a German scientist who said to be a patriot during the World-War 1. He put all his effort to invent the way of creating Ammonia‚ that to help Germany his country to defeat the enemies. And also as the creation of making Ammonia‚ he won the Nobel Prize in chemistry in 1918. Haber was born on December 9‚ 1868 in Breslau Germany. After the completion of his University studies‚ he worked for

to help even with chemical weapons and so if everyone stopped war then they will not use‚ and if there is war then you are not doing anything you will die from the enemies. During World War II‚ in occupied Manchuria‚ the Japanese imperial army (7 Haber Essay (AB)) uses chemical weapons to kill Chinese people which might be terrible but this is how they can tested on Chinese prisoners of war‚ many of whom died horrifically as a result. So we can see how terrible but they need to do this so that they

Fritz Haber (1868-1934) Born in December 9‚ 1868 on Bresalu‚ Poland in a Jewish family‚ Fritz Haber obtained his Ph. D. in Chemistry from the University of Berlin in 1891. From his early childhood‚ he was very fond of literature and that inspired him to compose verses. He joined the Federal Institute of Technology situated in Zurich for pursuing more knowledge on chemical engineering and made himself master of the contemporary modern chemical technologies. He innovated a new method to combine

7.4 Case Study: The Haber Process: Ammonia for Food and Bombs From: Eros Wang To: Ms. Irumekhai Date: March 30‚ 2012 1. Suggest five factors that could affect the production of ammonia in the Haber process. Explain the effect of each factor‚ using rate theory. The Haber process itself is a delicate balancing act because of all the factors that affect the yield of ammonia. In the Haber process‚ the nitrogen‚ hydrogen and ammonia are in equilibrium. So five factors that affect the

Synthetic fertilizer requires a plentiful supply of nitrogen‚ inventing a process to fix it in ammonia was daunting. Attempts were made for over 100 years. Then in 1909 Fritz Haber‚ a German chemist‚ solved the problem in principal. In 1910‚ Carl Bosch‚ pioneering new engineering methods‚ commercialized the process. Known as the Haber-Bosch Process‚ it is now responsible for growing about half of the world’s food. It was one of the greatest inventions of the 20th century. Without it‚ 30-40% of the world’s

The application of this new technology if thought beyond common sense is much more unclear. It has political‚ economic‚ nutritional and military aspects. Theses aspects merged during the Great War in resulted in the lengthened the war for an additional war and extending the industrial destruction. The technology had an obvious effect on public life‚ the question is if it was in an authoritarian

Almost everything in our world has some of their origins from chemicals‚ scientists in the chemical industries are always working to find ways to make these chemicals useful to us‚ they bring improvements into daily use substances like paints‚ medicines‚ cosmetics and plastics‚ so that they are more environmentally sustainable‚ and efficient. Scientists employed in the chemical industry trained and specialising in chemistry are called chemists. A chemist can gain expertise in a range of chemistry

Cycle Although some people may think that translations of original texts will ruin the meaning and the style that the original author wanted to present‚ it is not true for Robert Pinsky’s translation of The Inferno of Dante. Pinsky’s translation is not only essential‚ but it also presents the same picture that Dante wanted to. Even more impressive is that Pinsky also takes in the style that Dante writes in while translating the text. Pinsky keeps in mind the specific interlocking rhyme scheme
