Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid. What I already know Magnesium reacts with most

Atomic Structure Quiz Sample Questions 1. Why do only the number of protons and the number of neutrons make up the atomic mass of an element‚ but not the electrons? We generally do not use the number of electrons when calculating the atomic mass of an atom because they weigh so little (precisely 1/1836 AMU)‚ and only in precise calculations are the masses of the electrons included in atomic mass. 2. What was the difference between Mendeleev’s table and Mosley’s new arrangement? Mendeleev arranged

Professor Caddell. WWII: The Decision to Drop the Atom Bomb On the morning of July 16th‚ 1945 the first successful detonation of an atomic bomb was recorded at White Sands Missile Range in New Mexico. The explosion from the blast yielded more power than twenty thousand tons of TNT and could be seen at a distance greater than two hundred miles away. (Atomic Bomb-Truman Press Release) Later that month President Truman met with other Allied commanders in Potsdam‚ Germany to negotiate terms that

people were left dead (Rossenfeld‚ n.d.). The causes of all of this were two atomic bombs dropped by the United States. At first glance‚ it may seem that dropping these two bombs was a terrible and horrific thing to do. However‚ the use of atomic weaponry was actually a necessity in how well our conflict with Japan played out. Without the bombs‚ we would have fought longer‚ and more lives would have been lost. Dropping the atomic bombs on

engineering achievement that has made a huge impact to today’s society is the Shippingport Atomic Power Station. The Shippingport Atomic Power Station was the first world full scale atomic power plant that was devoted to exclusively to peacetime users only. The power station started its production December 18‚ 1957. It took thirty two months to create the power station and it cost 72.5 million dollars. The Shippingport Atomic Power Station ground was broken in 1954 during dedication ceremonies by President

America has always‚ and most likely will always place a high value on American lives. In order to protect these lives and to insure that the world is safe for democracy‚ American leaders had to make a very tough decision‚ whether or not to drop the atomic bomb on Japan. This act would essentially be trading Japanese lives for American lives. The Japanese‚ who were the aggressors‚ much like the Germans‚ were not sympathized with. They were responsible for hundreds of thousands of American casualties
