Stone Table

Introduction I am the information security specialist for a company that develops software X. Software X is the leading operating system in mobile devices. Unfortunately, our company believes Mr. McBride, a former employee stole product X source code for financial gain. As such, I have been tasked with leading the forensic investigation in this matter. Analysis Interview During an investigation is imperative that potential witnesses are questioned to gather essential information needed in the…

Atoms and the periodic table. 2014) Gold: Au, Arsenic: As, Molybdenum: Mo, Barium: Ba, Lead: Pb, Niobium: Nb, Technetium: Tc, Rhodium: Rh, Scandium: Sc TASK 6 The periodic table distinguishes metals from nonmetals, as the metals are present on the left hand side of the…

Based on Physical and Chemical Properties, Determination of Identities of Zinc, Sodium, Beryllium, Copper and Boron By: Shreya Uppala, Lizzy Jolly, and Kyrie Harrell Results: The first element we tested was zinc. Since zinc was already known, the density was stated to be 7.13g/mL and the hardness was a 2.5 based on the Mohs Hardness Scale. No magnetic attraction was observed when in contact with a magnet. Zinc had a shiny appearance with a light gray color and the strips of zinc added to…

FePO4 stands for Iron(III) Phosphate. Although α-FePO4 and β-FePO4 may sound quite similar as they may only differ in terms of the α and β, they β are actually very different in terms of the crystal structures and crystal chemistry of quartz. Based on the research article which was provided in coursera, it states that FePO4 is studied across a range of temperatures ; 294K to 1073K by neutron powder diffraction. The different range in temperature shows different structures. For instance, at…

Paragraph 1 This essay will evaluate the Haines et al. Also, the essay will discuss about how the structure of FePO4 will change at various temperature ranging from 294K to 1073K. FePO4's A cation is a transition metal, thus it is not the same as other α-quartz isotopes. FePO4' has α-quartz structure which is tetrahedral when it is at a very low temperature. Under huge pressure, FePO4's structure goes through a phenomena called β-phase which it became a more condensed octahedral structure.…

Understanding of multiplication facts is essential to have down by fourth grade. Knowing the times tables and being able to fluently recall immediately is needed throughout the entire year because of PA Mathematics Standards beginning with multiplication of multidigit numbers. There were students in my fourth grade classroom that had yet to be fluent with their multiplication facts, and it was necessary for them to have it down, for everyday mathematics and for the PSSA’s. I discussed with my…

Aquifers can predominantly be slowly replenished excluding the occasions these resources are drained. In the instances where the aquifers are drained, they can collapse and cause many ground collapsing events. Brian Howard describes how the water table, level of ground water, has dramatically deteriorated from 500 feet to 1000 feet in Central Valley, and the rate for drilling the wells is at a costly rate of 300,000 dollars per well.(Dimick pg 4). At rates so high, drought has the potential to…

explores each of the elements on the periodic table. The Disappearing Spoon focusses on the history of the Periodic Table by telling stories that show how each element affected the scientists that discovered it. For each element, Kean supplies an extensive backstory for its foundation, the common (or uncommon) uses of the element and other useful factoids about the matter. The author begins the novel with a physical description of the Periodic Table as a whole; he discusses the names of the…

The name is derived from the Greek 'helios' meaning sun, as it was in the sun's corona. Helium is a gaseous chemical element,with a symbol of He. Its atomic number is 2 and atomic weight is 4.0026. Helium is one of the noble gases on the periodic table. It’s the second lightest element. Helium is a colourless, odourless, insipid and non-toxic gas. It’s less soluble in water than any other gas. It’s the less reactive element and doesn’t form chemical compounds. The density of helium vapour is…

The element that I choose for this project is called Strontium. Strontium is a chemical element with the symbol (Sr) and it has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons.…
