ISIS verse Al-Qaeda and Aum Shinrikyo—Using Chemical Weapons: In attempting to answer if ISIS’s apocalyptic views of the world paired with their willingness to acquire and use chemical weapons can prove to be evidence that the group will seek and use nuclear weapons, comparing ISIS to al Qaeda and Aum Shinrikyo is necessary. Al- Qaeda followed a similar trajectory as ISIS in their pursuit and use of chemical weapons. In 2001, a computer was found at an Al Qaeda safe house…

thisi group because they are not always inert, or chemically inactive. the first element in this group is the element Helium. Helium has an atomic number of 2, and the chemical symbol for helium is He. helium is in the first period. The second element in this group is neon, which has an atomic number of 10. the chemical symbol is Ne, and is in period 2. The next element…

Temperature and pH will affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different…

Since the naming of the dinosaurs in 1842 it has been thought that their metabolisms were similar to current day ectothermic, cold blooded reptiles., In the 1960’s- 1970’s; however, it started to become apparent that an endothermic metabolism (warm blooded, like mammals) is more conformable with new evidence and observations. Originally, predictions on the paleothermometry of dinosaurs was based on the physical performance such as the estimation of running speed from trace fossils as well as…

Draw resonance structures showing all the positions at which the positive charge is delocalized on the aromatic ring in the phenonium ion. If a methoxy group (-OCH3) or a nitro group (–NO2) were substituted in the 4-position on the aromatic ring, how would the stability of the phenonium ion change? Compare methoxy substituted, nitro substituted and unsubstituted, and order them by increasing stability. Explain your answer thoroughly. 2) Benzopinacol and benzopinacolone have nearly…

Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of…

Imagine trying to figure out one possible combination to a mixture, when there are over 100 possibilities. The 8th graders had to look at the physical and chemical properties, to somehow figure out the mixture. A group of students thinks that Baking Soda and Citric Acid is what’s in the mystery mixture. That group thinks that Baking Soda and Citric Acid is in it for a lot of reasons. One reason is that the mystery mixture has circular round objects in it and the Citric Acid is circular and…

Mercury Claiming the life of Karen Wetterhahn, this chemical element has been proven mesmerizing but also fatally dangerous. Today I will be talking about the physical and chemical properties of Mercury, How the properties of mercury are useful in society, and the harmful effects mercury has to the human and environment. Mercury has 5 main physical properties including color, luster, conductivity, surface tension, and density. The chemical properties of Mercury include toxicity, oxidation,…

The unknown compound we received consisted of white crystal-like particles and was a solid at room temperature. During the smell test, we did not receive any indication of a distinct smell, thus concluding that the compound is ionic. The solubility tests indicated that the compound was soluble in water, NaOH, and HCl and non-soluble in acetone and toluene as shown in Table 1. The compound was soluble in water indicating that the compound is either polar or ionic, but not soluble in toluene or…

Contrary to the title, the discovery of astatine was anything but a momentary process. Many scientists discovered different astatine isotopes, atoms with the same number of protons but differing numbers of neutrons, but were unable to either reproduce their results or keep the isotope in existence for any useful amount of time. After decades of possible discovery and rediscovery, astatine was officially included in the periodic table of elements with the abbreviation At and an atomic number of…
