Abundance of the chemical elements

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…

“All animals are equal, but some animals are more equal than others.” This quote was written by George Orwell in his book Animal Farm, one of Orwell’s most famous novels. Throughout history the subject of a distant dystopia has always been explored in many works of literature. The possibility of humanity falling into a bleak and totalitarian society has always fascinated readers. These stories and themes can come to define an author and their legacy as a writer. There is no greater example of…

An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and…

3.3. Mulliken Atomic charges analysis Mulliken atomic charge calculation has an important physical property of the quantum chemical calculation of molecular system because of the atomic charge effect, electronic structure and more a lot of properties of molecular systems [19].The possible molecular bonding of a compound depends on the electronic charge existing on the chelating atoms [20]. The charge changes with basis set presumably occur due to polarization. The charge distribution of (C20 is…

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.…

and water we drink. A substance is a kind of matter that cannot be separated into other kind of matter by any physical process. For example sugar or salt solution, air, water, water in oil. A pure substance consists of a single type of particles (Elements and Compounds).Mixtures are substances formed when different kinds of particles come together. When a substance consists of…

The purpose of the lab was to determine which unknown substances were ionic compounds, if any, using 4 different methods. This lab was to determine which of the three unknown substances (X, Y & Z) are ionic compounds and which are not ionic compounds. In conclusion unknown Y is an ionic compound and unknown X and Z are not ionic compounds. In order for a substance to be an ionic compound it must have a high melting point, it must be brittle, it must be soluble in water, it can not conduct…

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 groups of elements…

Akasha is the word we use to mean the Element of Spirit. The are five Elements used in magic, Air, Fire, Water, Earth and Spirit or Akasha which is the combination of the other four Elements. Without Akasha you could not have the other four Elements because Akasha or Spirit is the principal element in everything. Akasha is the source of all energy, energy that has not yet taken form or substance. Akasha is energy without form. To me Akasha means the spirit or universal force which is the base…

Explain this using the information in the chemical equation. The magnesium did not leave a significant odor because it is a pure metal, and pure metals are known for not leaving a distinguished scent when burned. 2MgO also tells us that oxygen is also the final reactant in reaction #2, and we know…
