Reflection Paper Being completely undecided in my career path, and since I have taken all of the available chemistry classes, when the opportunity to job shadow a water operator at the Emlenton Water Treatment Plant arose, I took advantage of it. Even with my knowledge in chemistry, I went into the experience knowing only that they use chemicals, such as chlorine, to treat the water from the river. I came out of the experience with a more selective career path and a much greater knowledge and…

What I have found about this experiment is some really interesting ideas and other ways to the experiment. Some other people use Sodium or other words, for Sodium on the periodic table this chemical is called “Na” other people use that to make the Elephant Toothpaste. The call it Elephant Toothpaste because it’s supposed to look like toothpaste and since it's so big and it looks like toothpaste so the first thing people thought of was Elephant Toothpaste. Is that it was so deadly and that it…

Chirality is a geometric property of some molecules and ions. A chiral molecule/ion is non- superimposable on its mirror image. The presence of an asymmetric carbon atom is one of several structural features that induce chirality in organic and inorganic molecules. Many biologically active molecules are chiral, including the naturally occurring amino acids (the building blocks of proteins) and sugars. In biological systems, most of these compounds are of the same chirality: most amino acids are…

Chemistry is a world many of us forget exist in our daily lives. We go about our routines, forgetting that chemistry plays a key role in our lives. As a skier, I noticed the unseen world of chemistry when I am preparing for ski races, waxing my skis. Preparing my skis for a race weekend requires applying multiple layers of wax to my skis. The wax we use is commonly a fluorocarbon mixture. In order for the wax to be saturated into the ski, the block must be melted with an iron. Once the…

Question: How do different surface areas affect bacterial growth? Hypothesis: I think that the bacterial growth will be different in terms of size, shape, type and color. I think that different bacterias will grow on each quadrant because each surface of collection has unique bacterias. The unique bacterias will contribute to the fact that the size and color of them will also be different. I also predict that the growth of bacteria on the toilet seat (1D) will have the most colonies because it…

The best way to determine which concentration of salt water is ideal for hatching brine shrimp is to create a controlled experiment. This experiment would utilize four containers of water including; a 2% salt water concentration, a 4% salt water concentration, a 6% salt water concentration, and a container of fresh water, to set a base number of brine shrimp hatchlings for the experiment. Besides containing the salt water concentration, and the brine shrimp eggs, each container should receive…

dopaquinone is converted to melanin in the hair follicles, skin and the retina. Tyrosinase is also responsible for the brown color that forms on the inside of fruits and vegetables after they have been cut. The tyrosinase catalyzes the reaction with oxygen and catechol. Catechol is an organic alcohol found in most plants. Tyrosinase and catechol oxidases have a binuclear type 3-cooper center.…

Glow sticks have many uses to them and many people use them in a number of situations as well. One important aspect of glow sticks is that they are water proof, so if you ever go scuba diving or just want something to light up in your pool then glow sticks are perfect for that. Another feature of them is that they do not require any batteries at all so they are very simple to use, and one final thing that is interesting about glow sticks is they generate an insignificant, or small, amount of…

Yes, I believe that using controlled fires to protect wild areas are beneficial. Controlled fires help maintain the health of an existing natural area containing native plants and they help manage weeds and other growth, which helps to reduce the risk of wildfires. Fire is one of the best outdoor management tools for invasive plant control. For over 10 years ecologists have been using this technique, which has spread to many other trained people to use as a tool. Woodlands, prairies, and…

Explain the difference between aerobic metabolism and anaerobic metabolism. Aerobic metabolism occurs in the cell’s mitochondria and requires oxygen, anaerobic metabolism occurs in the cytoplasm and it does not require oxygen. During aerobic metabolism the hydrogen and carbon molecules from dietary fats, proteins, and carbohydrates are mixed with oxygen to form carbon dioxide and water as energy is released. These end products that are produced during aerobic metabolism are to some extent…
