Inorganic chemistry

I decided to pursue this degree because my first chemistry teacher inspired me. She is an amazing woman. Previously she had the job that I would eventually like to have and has a family, productive life, and also able to maintain all of her hobbies. I want to pursue this degree because I want to have a successful life like hers. I also want this degree because I love chemistry I believe that chemistry is my true passion. I have loved chemistry from the moment I started it. I wish to pursue a…

The purpose of the whole lab is to use my knowledge of the periodic table to determine the identity and physical properties of each unknown element. To find the unknown elements we looked at the characteristics of the other elements and grouped the ones that were similar and belonged in the same column. By looking at the characteristics of the unknown elements if it seemed to belong in a group with others with a blank we assumed it belonged there. Mendeleev was a scientist who came up with the…

Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the…

chemist from Russia who lived in poverty and was the only one of seventeen siblings to attend school. Mendeleev then created the first periodic table from his finding through periodic law, which he also created. Medeleev was a major contributor to chemistry through the modern…

In order to complete this experiment, students had to provide a great amount of focus and a good understanding of the procedures, which were, along with the materials, very detailed. With this being said, because most of the materials had similar names, it was important for students to not manipulate the lab by mixing up the reagents, which would completely ruin the experiment. The important factors that influenced the success of this experiment included the following: 1) 100% transfer, 2) 100%…

The scientist’s want to see if certain sugars affect the amount of fermentation caused by yeast. The problem statement is; in which of these sugars, monosaccharides, disaccharides, or polysaccharides, will fermentation by yeast occur the best? The independent variable is the variables the scientists can control, so the scientists decided to use certain sugars, such as dextrose, maltose, and lactose being the IVs (Independent variables). The scientist’s Dependent Variable (DV) is the outcome of…

Somewhere in between the years of 460 BC and 370 BC a man named Democritus first introduced the idea of an atom. He was the first person to say that everything is made of atoms. He also said that atoms are indestructible and that the changes we see in substances are just the atoms moving. Democritus said that the shape of the atoms give substances different properties. Democritus’ work, however, did not survive through the Middle Ages. Democritus had no real evidence to prove his theory, but he…

Energy Drink Intake Effects on PTC Tasting Abstract PTC sensitivity experiments has been used throughout the years to show that Mendelian traits shows dominant inheritance. Individuals are able to either not taste PTC, slightly taste PTC or strongly taste PTC. This shows that sensitivity to PTC among tasters varies significantly. However, while genetic variation in taste controls whether a person is a non-taster or taster there are many factors that contribute to being able to taste PTC. In…

Concentration of Acetic Acid in Vinegar Nalebra Barnett, AAHCA, BSHA University of Central Oklahoma General Chemistry II Lab March 28, 2017 Dr. Lane Whitesell Lab 12. Concentration of Acetic Acid in Vinegar. This laboratory is to determine the concentration of acetic acid in vinegar using molarity and percent by mass of acetic acid in vinegar. This means, vinegar is a crucial solution of acetic acid (HC2H302) in water. Molarity (in mole/L), or mass percent expressed the…

Dear Amma, How’s everyone doing? I’m having a lot of fun at school. My hardest class right now is probably my organic chemistry class. You remember the organic chemistry class that I took in high school? It’s a little like that, but definitely harder and more focused on real-world applications. The course actually includes a weekly three-hour lab with its own one-hour lecture. I think it’s a pretty great course because we learn techniques that are used in actual labs. Last week’s experiment…
