From an environmental view point, cell phones can affect our society in various ways. For instance, the debate on whether or not to include cell phones in schools has been going on for a long time., Sso much has happened to prove that cell phones (or any other electronic device for that matter) are suitable for classrooms. Recently, schools across the United States have begun to establish BYOD (or Bring Your Own Device) (BYOD), where students can bring their phones to use while class is in…

The Grignard reagent is an organometallic compound as it includes a carbon atom bound to magnesium and a halide, usually bromine. Grignard reagents must be prepared in an aprotic solvent, such as diethyl ether or THF, because the MgBr, is a strong nucleophile and thus a strong base. There must also not be any water in the solution for the same reason. As such, the solvent must…

Chemistry ERT - ITEM 3 Item 3.1 and 3.2 – Graphs The trend for the number of electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is…

by 60 percent. Obviously slavery ending was a great thing that came from the Civil War. Also the union was rejoined. Many things were created in the medicine departments of battle fields medicines were created that are still used today such as bromine which had an original cause to fight against gang green. Things were also developed technologically. The Civil war was the first war fought in which the president could give direct orders the generals. This happened because of telegraphs,…

He also contributed to World War 1 by helping invent the usage of gas warfare. At first he tried using nitrogen then he stared experimenting with bromine. Then later found out that chlorine had all the answers he was looking for it turned you body different colors and weakened the body to the point of death. Haber was a German and his wife did not like the fact that his experiments were killing, so…

Thanks to Rachel Carson’s book, Silent Spring, we now have many laws, guidelines, and even bans to ensure the safety environment and those who live inside it. Recently, some controversy has developed over the use of a pesticide known as Naled. Naled is currently being used to treat areas plagued by mosquitoes carrying the Zika virus and some people are debating whether the use of Naled should be discontinued due to its toxicity. The use of Naled is safe for our environment and should continue to…

Content Stoichiometry is the relationship of the masses of the reactants and products in a chemical reaction. For a given mass of a substance in a reaction, the mass of any other substance in the reaction can be obtained using the coefficients of the balanced chemical equations and the molar masses of the substances involved. The amounts obtainable from a balanced chemical equation are called stoichiometric amounts (Villamar Jr., 2004). As what was said in the introduction, the first topic that…

Electrochemical Performance. To evaluate the electrochemical behaviors of the highly open framework of the as synthesized LTH on nickel foam electrodes NCA-L-@NF, NCA-L@G-NF and NCA-L@ BG-NF with three different feeding mole ratios , which is the best morphological foundation for fast redox reaction and charge accumulation, its potential application in high-performance supercapacitor has been investigated by cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance…

Being a relatively new element when compared to many other known elements, Germanium has only been documented element since 1886. It has little to offer in the way of health benefits, but it still remains a useful element. Chemical Properties Germanium is the thirty-second element in the periodic table represented with the symbol Ge. It is located in the fourth period under group fourteen. Along with other elements like Silicon and Arsenic, Germanium is a metalloid. As a metalloid, Germanium…

 Comment: The three bonds (one solid line, one wedged line and one dashed line) that are attached to the + carbon atom are turned inside out. If the starting material has Br on the right side of the + carbon atom, the final product will have OH on the left side of the + carbon atom and vice versa.  Comment: There is only one hump for the energy profile of an SN2 reaction. As we shall see later, there are two humps for the energy profile of an SN1 reaction. One easy way to…
