In ww2 ‚ the atomic bomb was dropped on japan to put an immediate end to the war and not draw other countries (i.e. the soviet union or china) into fighting combatively against the U.S. As far as foreign relations go‚ it proved to the world that the U.S was the most powerful country in that time ( superpower) . This also relates to several years later during the cold war. It prompted the Soviet Union to develop their own nuclear warfare. (i.e us comes out with hydrogen bomb and a year later USSR

procedures: 1. Hydrogen G. When hydrogen gas comes in close contact with fire‚ it generates a loud noise similar to a popped piece of popcorn and it blows out the flame. 2. Oxygen B. When manganese reacts with H2O2 small bubbles form around the pieces of manganese and carbonates the whole solution. E. When I put the glowing toothpick in the oxygen gas it caused the toothpick to light up instantly for a short period and then made it glow brighter red. 3. Hydrogen and Oxygen Mixture

hydrochloric acid In the lab‚ zinc granules react fairly slowly with dilute hydrochloric acid‚ but much faster if the acid is concentrated. The catalytic decomposition of hydrogen peroxide Solid manganese(IV) oxide is often used as a catalyst in this reaction. Oxygen is given off much faster if the hydrogen peroxide is concentrated than if it is dilute. The reaction between sodium thiosulphate solution and hydrochloric acid This is a

Decomposition of Hydrogen Peroxide by Potassium Iodide Brief Description: Two solutions are mixed resulting in an eruption of foam resembling a huge stream of toothpaste. This is the classic “Elephant Toothpaste” reaction. Purpose/Goal: Procedure presents an example of a catalyzed reaction. Explanation of Experiment: The rapid evolution of oxygen gas is produced by the following reaction: 2 H2O2 (aq) = 2 H2O (l) + O2 (g) + heat The decomposition of hydrogen peroxide in the presence

NO THANKSGET THE APP how heat affects metal when it is being welded (peasecha) Charles Pease 3-29-16 English 10 How heat produced from welding affects metal The heat produced from the welding process can cause deformation and can also cause changes in the metal at a molecular level. This can make the metal brittle and even deform it. When the arc is struck and the metal starts to become molten it reaches temperatures in an excess of 8‚000 degrees fahrenheit and such a large input of heat
