Chemistry Essay

Introduction Chemistry is one of the broadest scientific subjects that are primarily focused on the manner in which matter interacts with energy. However, chemistry tends to be more focused on the study of the properties of matter as well as the interaction between various types of matter. The interaction is often facilitated by the reactions that involve either electron loss or electron gain, as described by the American Chemical Society (2014). Unlike other sciences, such as physics, chemistry…

the objectives (listed in your introduction) and main results of this experiment. [Hint: make sure to discuss what you learned about the size of atoms/molecules based on the measurements made in this laboratory exercise.] What is the Scale of Chemistry? Worksheet Significant Figures, Scientific Notation and the Metric System Name(s) _______________ _______________ Section __________ 1. Convert each of the following numbers to standard notation. In the parentheses, tell how many…

Chemistry, oh chemistry! Chemistry is an interstmig subject. Withourt it we would not know many of the thigns we do today. However, with chemistry comes a lot of studying and hard work. There are three bonds in chemistry ionic, covalent, and hydrogen. Do not ask me why they named them this because I am unble to tell you this. However I can tell you that SCl2 is an ionic bond and NaCl is a covalent bond. Well, that is that the atoms in them form those types of bonds. Hard to belive I know, but…

is a lot of chemistry involved. The various processes that a forensic procedure requires includes basic skills and knowledge from chemistry. Since chemistry and forensics are so closely related, many of the same concepts are used in each field. That is why it is important to go into more detail to see what type of chemistry has to deal with this. It is very rare that there is a forensics specialist investigating a crime scene without there being any type of chemistry involved. Chemistry is to…

The Chemistry of Emotions Even though we often think of our emotions as part of our own conscious, they are simply chemical reactions to stimuli in the mind, and depending on the event and who we are the chemicals released and emotions we perceive as result are always different.The emotions in our brain our vital to our survival. Emotions are simply the quickest way to get our body to react with the environment around it. For example, if we feel fear we are able to react to the oncoming…

Content Stoichiometry is the relationship of the masses of the reactants and products in a chemical reaction. For a given mass of a substance in a reaction, the mass of any other substance in the reaction can be obtained using the coefficients of the balanced chemical equations and the molar masses of the substances involved. The amounts obtainable from a balanced chemical equation are called stoichiometric amounts (Villamar Jr., 2004). As what was said in the introduction, the first topic that…

Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. The structural evolution of FePO4 arises due to the deviation in temperatures from 294K to 1073K via a process known as the neutron powder diffraction. This happens when the temperature of 980K is reached to result in the α to β transition. There are however certain observations of discontinuities in structural parameters during this transition. The stark contrast is that during the α phase, there…

The carbodimide chemistry reaction involves first the activation of the carboxyl group using 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide EDC and then a covalent reaction between free amino group and activated carboxyl group in PEG-EGFR and PF0-HNC respectively [42]. In…

Green chemistry principles were applied to multi-step synthesis reactions; these reactions included the bromination of trans-diphenylethylene, bromination of ethyl trans-cinnamate, and debromination of 1, 2-dibromo-1, 2-diphenylethane. These reactions featured a reflux set-up, which allowed the reactions to occur at higher temperatures and aided in the prevention of the evaporation of the solvent and the loss of product thereby increasing the efficiency of the reactions. Furthermore, the…

the bases and acids in my head to figure out what this lab meant exactly in my AP Chemistry class. Science has always fascinated me but when I decided to take this course, it was a whole new level. My chemistry teacher told me this course would be a challenge and it wasn't until I was in the course, that I realized he was completely right. Sure it was a challenge, but it was also fascinating to understand the chemistry behind all that exists and knowing that every single object is made up of…
