Fritz Haber was a German chemist of Jewish origin who developed the Haber process, which was the first industrially perfected method of synthesizing Ammonia from Nitrogen and Hydrogen gases. This invention was of importance to the synthesis of fertilizers and explosives. The food production for half the world's current population depends on this method for producing fertilizer.Haber is also remembered to history as the "father of chemical warfare" for his actions during the Second Battle of Ypres and for his years of pioneering work developing and weaponizing chlorine and other poisonous gases during World War I. Science and technology have the potential to be used for good or bad. Fritz Haber won a Nobel Peace Prize for what he did.
Perhaps some of those tubes failed to explode and instead skittered out of the fires, propelled by the gases and sparks produced by the burning gunpowder. During the 17th century, the scientific foundations for modern rocketry were laid by the great English scientist Sir Isaac Newton (1642-1727). Newton organized his understanding of physical motion into three scientific laws. The laws explain how rockets work and why they are able to work in the vacuum of outer space. Newton's laws soon began to have a practical impact on the design of rockets.
Atomic Bomb DBQ As the end of World War II was coming, the United States created one of the most powerful and destructive weapon known in humanity. The weapon, which was called the atomic bomb, was used on Hiroshima and Nagasaki. President Truman decided to drop the atomic bomb in order to intimidate the Soviet Union, showing that the U.S. was a very strong military. In addition, it was a strictly military measure designed to force Japan’s unconditional surrender, because Truman knew that the Japanese would not surrender, and was almost give little option into using or not using the bomb. Japan had also been warned that the bomb would be released on Japan, but made no motion to consider surrendering.
The reason that the HCL was able to dissolve the copper penny was because the HCL had a higher affinity for electrons then the copper did. When the HCl stole the copper electrons the penny melted. This is also the reason why the aluminum balls melted when dropped in the test tube filled with HCL. This chemical reaction between the aluminums oxide coating and the HCL will create Hydrogen as a bi-product. We knew that the gas was hydrogen because of the loud pooping sound that hydrogen created when it came in contact with the match.
Some of the inventions are as follows: tea, gunpowder, a compass, chopsticks, bristle toothbrush, silk fiber, paper and printing, publishing, a seismograph (an earthquake detector), porcelain, acupuncture, lacquer, the wheel barrel, the abacius (calculator) and toilet paper. The inventions and contributions are essential building blocks of the world today. I believe the four ingenious or innovative ones are gunpowder, paper, the compass, and printing. According to About.com, gunpowder was discovered by the Chinese, during the Han Dynasty. It was used to create explosions at festivals.
Rather, the Chinese alchemists were searching for an elixir of life. In other words, they were combining different chemicals in the hope of unfolding immortality in humans. On the contrary, ancient Chinese alchemists’ mixture of potassium nitrate (saltpetre), charcoal and sulphur was not the elixir of life but the foundation of an explosive powder. By the 12th century the Chinese was able to increase the levels of nitrate within gunpowder to burst cast iron containers alternately creating gunpowder-filled grenade bombs. In early history, gunpowder provided leverage for military conquest.
Mr. Bodner states that French Physicists Jean Baptiste Perrin was the first to use the term Avogadro’s number. Based on his work on Brownian motion in 1909, Perrin reported an estimate of Avogadro’s number. To accurately determine Avogadro’s number requires the measurement of a single quantity on both atomic and macroscopic scales, with the use of the unit of measurement. This was possible because American Physicist Robert Millikan measured the change on an election. The charge on a mole of electrons for some time and is the constant called the Faraday.
Introduction Introduction Although the term ``weapons of mass destruction ' was first used by the London Times in 1937 to describe the carnage resulting from a German Air Force attack on a town situated in Guernica , Spain , the term itself is now widely associated with non-conventional weapons with devastating capacity . Following the use of the atomic bomb on Hiroshima and Nagasaki , Japan at the conclusion of the Second World War the term ``weapons of mass destruction ' became synonymous with the atomic bomb and later with the hydrogen bomb . Today , all biological , chemical , radiological and nuclear weapons constitute weapons of mass destruction . The US Department of Defence in its Dictionary of Military and Associated Terms describes weapons of mass destruction as follows : ``Weapons that are capable of a high order of destruction and /or of being used in such a manner as to destroy large numbers of people . Weapons of mass destruction can be high explosives or nuclear , biological , chemical , and radiological weapons , but exclude the means of transporting or propelling the weapon where such means is a separable and divisible part of the weapon ' History of the Use of Weapons of Mass Destruction Although the first use of nuclear weapons was the atomic bombs dropped on Hiroshima and Nagasaki at the close of the Second World War , there have been numerous accounts of the use of chemical weapons throughout history .
In the new day and age going green is significant. We should not continue to allow the use of these dangerous chemicals from Styrofoam on our properties, in our neighborhoods and our bodies. Styrofoam was invented by an accident during world war two by McIntire, who was trying to invent a good electric insulator and was trying to make a new rubber-like polymer by combining styrene with isobutylene, a volatile liquid, under pressure. The result was foam polystyrene with bubbles, 30 times lighter than regular polystyrene. So, in 1954 the Dow Chemical Company introduced Styrofoam products to the United States, which was used to provide better installation for houses.
Materials: fluorescent screen gold foil radiation source (positively charger alpha particles) Procedure: Rutherford set up an alpha source. The alpha part ices ere helium nuclei, two protons and two neutrons. A lead block with a slip served as the source. A radioactive substance giving alpha particle emission was put inside. The slit acted as the only means of escape for the particles.
