Tricia Nguyen Mr. Seals Honors Chemistry - Period 6 23 November 2014 A Game Changer or Simply a Danger? With every choice, there is a fine line between making progress and losing everything one has worked for. The use of nuclear energy is the very epitome of this. While it provides an alternative to the energy sources we use today, nuclear power comes with great risks that can take a lot to fix. However, I believe that with the proper precautions in place, we should continue the use of nuclear…

spheres. He explains that Merlin goes through a sort of rebirth by Geoffrey and even in the Arthurian legend he is cast differently as well. It is during this period that the characters of the Arthurian legend come to be. Knight looks at Robert de Boron, who was a Burgundian writer, and his rendition of Merlin. In his imagination Merlin becomes a Christian authority. He has more authority and is able to find new ways to apply his knowledge. He is depicted as a knowledgable figure but also a…

of 9-fluorenone using sodium borohydride to give 9-fluorenol will be examined. This reaction involves the transfer of a hydride ion from borohydride ion to the electrophilic carbonyl carbon with the accompanying transfer of the electron deficient boron atom to the carbonyl oxygen.1 The reaction is shown below: 10 is 9-fluorenone, 11 is the intermediate borate salt, and 12 is 9-fluorenol. 2 Experimental Before coming into the lab, a stoichiometry table was created with information for each…

benefit to the world’s growing population” (Phillips, 2008). The crops benefit from genetically engineered DNA because they mature faster resulting in crop production to be higher and faster. Phillips also found that crops can tolerate “aluminum, boron, salt, drought, frost, and other environmental stressors, allowing plants to grow in conditions where they might not otherwise flourish” (Phillips,…

Figure 1 shows the relation between density ρ and molar volume Mv as a function of copper oxide. From this figure, can be observed that the ρ and Mv decreased with the increased of copper oxide content replacement the lead oxide. The decrease of density due to the molecular weight of CuO is lower than the molecular weight of Pb3O4. The decrease of the molar volume due to the decrease the number of oxygen and may be the ionic radius of copper ions less than the ionic radius of lead ions. The…

Quantification of Iron in Whole Grain Cereal Jacob Rickman and Yasmeen Coan Submitted to: Curt Zanelotti CHEM 1045, Experiment No. 12, April 15, 2016 LABORATORY WRITTEN REPORT Honor Code Signature: _________________ Objective In this experiment, we gained an understanding of the relationship between chemistry and food products while developing and enhancing good lab techniques. We applied dilution concepts to carry out the experiment. By using these concepts and techniques, we created a…

Discuss fitness tests or methods of evaluation that should be used to assess the client, providing rationale for your recommendations. Be sure to address the specific conditions presented by your client. It will be important to consider that his body is still going through puberty when designing a program for him. This offers a great opportunity to encourage him though, as this is when he can set up what the status quo will be for his adult life regarding his physical fitness and overall…

Elements above the atomic number 95 are produced in a particle accelerator by accelerating a small charged nuclei (such as Helium, Boron or Carbon) in a particle accelerator to combine with a heavy nucleus (often of a previously made transuranic element) target. The transuranic elements have short half-lives as the atomic number increases. The smaller nuclei combines within the target nucleus, creating a new unstable nuclide or radioactive isotope. The high speeds are required to overcome the…

Evolution of the Panels Solar power is not a new concept—two thousands years ago our ancestors would concentrate the sun’s heat with glass or mirrors to light fires or heat water. It wasn’t until 1839 that Edmond Becquerel, a French scientist, discovered what is known as the “photovoltaic (PV) effect,” (US DOE EERE). While experimenting with an electrolytic cell that consisted of two metal electrodes placed in an electricity-conducting solution, he noticed that electricity-generation increased…

Atomic structure AC1.1 1. Produce a table showing each sub-atomic particle with their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A…
