Chemistry

Chemistry has many different career paths and chemists specialise in a diverse range of different areas. Chemistry is a science that deals with the properties, composition, structure of elements and compounds, thereby; chemists use this information to develop new materials and substances. There are a number of career paths in chemistry such as biochemistry, industrial chemistry, electrochemistry, polymer chemistry and much more. While all the other field names speak for themselves, industrial…

In this lab, students learned that in a combination reaction, two or more substances react to form one substance. This can be seen in reaction #2. In reaction #2, magnesium reacts with oxygen to produce magnesium oxide. Although the students can only see magnesium and magnesium oxide, the students were informed on the lab sheet that oxygen was also one of the reactants. This reaction allowed students to see how two substances, magnesium and oxygen, react to produce one product, magnesium oxide.…

Paragraph 1 This report aims to study the symmetrical distinctions, crystal structures and chemistry of α‐FePO4 and β‐FePO4 as well as any alteration to FeO4 and PO4 when there are modifications to temperature. It also seeks to justify the tilting of the tetrahedral. The article by Haines shows that he had studied the iron phosphate, FePO4, at temperatures from 294 K to 1073 K and had found that the turning point between the 2 phases is at 980 K, where FePO4 takes on the alpha phase at…

Qn1 Ans Decision tree analysis will involve step determination of the chemical and physical characteristics of this chemical. By knowing them, it will be very easy to determine the best control method to be employed. Firstly, the compound is corrosive and it therefore suggests that it is highly reactive and use of water and any other chemicals that can lead to an undesired chemical reaction will be ruled out. Also, the spilled chemical is producing fumes, mostly it suggests that it is either a…

1 There was no smell 2 When I pour the oil in the water I noticed the oil started to bubble to the top. So I got to stir the oil that’s when there were smaller bubbles. As I smell the water there was no smell to the water. 3 Pouring the vinegar in the water there was one change that I notice the water was darker after I added the vinegar. There was no smell even though I added to the water. 4 When I added the detergent to the water it started to look cloudy and there was bubbles. 5 I notice the…

Standard solution is the solution that is been made by dissolving a precise mass of reactant meaning the starting substance in a chemical reaction, and it is important that the mass is weighed accurately into distinguish volume of water that will be used. This tells us that if the concentration of standard solution is accurate then it can also be used to work the concentration of a different solution that it can also react with. Its concentration is generally given in mol dm-3. Standard solution…

Organic chemistry is a challenge. So many people have told me how demanding and scary it is, and even though I was terrified coming into this year, I am ready to take on the challenge. It is a challenge that will hopefully end up with a rewarding learning experience as well as prepare me for life after college. Throughout this course, I think that it is vital to know how you learn best, what the professor is expecting of you, as well as how the class is structured and the policies within it.…

In these two weeks, I observed a chemistry class taught by Angela Willson. The main topic for these two weeks was Matter. I was very interesting to observe the chemistry class because chemistry is major. The first thing that got my attention when I entered the class, the teacher wrote a long list for everything they would do as numbers of orders, and in the top of the board she wrote“ Agenda-Day5”. Usually, teachers use objectives, so it was good for me to learn a new word. The list became…

There are numerous scientists who have positively impacted the field of Chemistry; from Robert Bunsen to George Washington Carver, chemists have and continue to shape the publics knowledge of Chemistry. However, one chemist stands out from all the rest because of his historical, societal, and person significance: George Claude Pimentel. Pimentel’s life, work, and contribution to Chemistry have shaped this field and impacted it in ways that other scientists have not. Background George Claude…

if people knew the best way to clean them. Pennies are made up of many things, some of which react with other things that make them have special properties. The properties that make pennies dirty are “...2.5% copper and 97.5% zinc”(Katherine’s Chemistry Blog). The copper in penny's makes them rust or oxidize.This happens when the copper in the pennies reacts with the oxygen atoms in the atmosphere which cause rust, therefor making them apear dirty,and vinegar…
