Alchemy was the earliest understanding of today’s chemistry. These two display Is Alchemy Chemistry? different pathways of thinking and rationalising rather than two diverse concepts. The practice of alchemy is the basis of chemistry, as it was a vital role of origin and evolution towards chemistry we know today. The comprehension of both alchemy and chemistry will aid in order to establish their connections and difference of opinion or belief. Discovering both histories of the two concepts will…

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.…

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.…

Joseph Priestley was a famous chemist. He was famous for inventing soda water, his writings about electricity, and his discovery of gases. Joseph was born on March 24, 1733, in Bristall. He died February 6, 1804 at the age of 70. Joseph is most known for his discovery of oxygen and for isolating it. Oxygen was not first discovered by Joseph, instead the famous Swedish chemist, Carl W. Scheele, in 1772. Joseph discovered Oxygen independently in 1774. Joseph published his findings in the…

The origin of the name comes from the word Scandia, which is the latin name for Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table and they are: metals, non metals, transition metals and gases. The chemical properties of Scandium are very similar to the rare earth elements. It reacts very quickly with acids and when reacting with oxygen, it tarnishes and burns to form…

created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even those who do not have a PhD in a science field. As the book goes on, Kean slowly unravels the mysteries of the periodic table in a way that is simple and almost easy…

The periodic table is a very identifiable symbol in everything science. There is one hanging in almost every chemistry class. But, the one we know is not what it always was. Before our modern periodic table there was the periodic table that Dmitri Mendeleev constructed. There are many differences and similarities between the Modern Periodic Table and Mendeleev’s Periodic Table. Just for example, the modern periodic table arranges elements in order of increasing atomic number. Mendeleev’s ordered…

____________ PD: _______ An Inventory of My Traits - Data Table Traits are observable characteristics we inherit from our parents. Some traits are common in a population (our class) while others are not. Every person has a different overall combination of traits that makes them unique. Some of the traits explored in the human population will be examined in this exercise. (Warm-Up) With a partner to help with observations, fill in the data table based on your personal traits. (If needed,…

clean, pretty, and welcoming. When we walked inside it was surprising. Compared to other burger places I have been, this one had an ambiance and the staff was so well trained and helpful. At the entrance a hostess welcomed us and accompanied us to our table. We did not have to wait even a minute and our server was already there asking for our drink orders. He was well trained and educated on every aspect of the menu. He was able to explain all the ingredients of every dish, give us an examples…
