Chemistry Essays

Many people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this

Chemistry is the branch of science that deals with the composition, structure and changes in matter. You are a product of chemistry, apparently, everything is! From the tiniest grain of sand to the heavenly bodies in the universe, the stars, the planets, they are products of chemistry, can you even envision a world without chemistry? Of course, you can’t, your mind is a product of chemistry too! It is also used in daily human activities, such as cooking. But even though I have stated some its uses

While I was in high school I struggled in AP Chemistry and AP Language and Composition. In AP Chemistry, I struggled with solving for the K value in equilibrium, in which I got help by going to the tutors in the school library after school. The tutor helped me out by showing me how to understand the examples in my notes and then by helping me apply the same technique of solving that was on the notes to the problems that were assigned to me as homework. This is the only reason why my AP Chem grade

Theoretical chemistry is an insightful mathematical tool to understand experimental facts and provide conceptual directions to experimentalists. The discovery of theoretical concepts came after several experimentations and attempts. Earlier progress of theoretical chemistry was narrowed due to the limitation of computational facility. The growth in the empower of electronic computers and softwares have increased the inability to unfold the problems of vigorous calculations into easier forms and enabled

Chemistry IA Background information: Introduction: Electrolysis it’s a chemical process that when you pass an electric current into a solution or a liquid that contains ions to separate substances back to their original form. The main components that are required for electrolysis to take a place are:  Electrolyte: it’s a substance that when dissolved in water it ionize and then it will contain free moving ions and without these moving ions the process of electrolysis won’t take place.  Direct

The isomers which can be inter converted solely by rotation about formally single bonds in a form of stereoisomerism in chemistry studies are defined as conformational isomers. This phenomenon in chemistry is called as conformational isomerism. Conformational isomers are stereoisomers which arise from the rotation about sigma (σ) bond (single bond). It is usually fast interconverting in room temperature, causing in different arrangements of atoms in three-dimension space. The isomers which created

Like most students, I start this course off with prior knowledge of Biology 1 and Chemistry 1, and am taking AP Physics C Mechanics this year as well. I did relatively well in Chemistry, my favorite part last year was learning how to easily do dimensional analysis! I loved participating in labs during class, but found that it was hard to write down information while observing the experiments taking place. I was usually allowed to take labs home to thoroughly finish them, something that has helped

Gummi bears may not be obvious lab material, but in Mary Hershey’s chemistry class, they’re popular fodder for demonstrations. When they go up in flames, students are fired up—to the point of applause. Such displays help Hershey’s Chemistry 1 and Advanced Chemistry classes at State High understand concepts and connect with a challenging subject. “Just last week, we lit methane bubbles to teach them combustion,” Hershey said. “So you can teach chemical ideas through demonstrations, and when the demonstrations

scholarship and research focusing on drug discovery and medicinal chemistry. My undergraduate training was centered on nutrition and food science. This is a broad discipline that draws on all of the basic sciences, but places significant emphasis on organic chemistry, biochemistry, and physiology. It was as a result of those studies that medicinal chemistry enticed me. I was keen on acquiring

Sodium carbonate (molecular formula: Na2CO3), is the water soluble sodium salt of carbonate. The pure product appears as a while, odorless powder with a strong alkaline taste. It has high hygroscopicity. It can be easily dissolved in water to form an aqueous solution with moderate alkalinity Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is

Measurements and significant figures are important in Chemistry because it shows how accurate something is, and it shows which place value is the estimated one if/when used correctly. In this lab, the density for water that was found is 0.99g/mL and the percent error was 1%, and 1% is good. An error that could have occurred while finding the density for water was that the measurement were not exactly correct because not everything is going to be perfect. The density for Copper that was found was

In addition to the discovery of latent heat being used for calorimetry, latent heat also brought about changes to the steam engine. As previously mentioned, Joseph Black worked closely to James Watt, inventor of the steam engine, doing several experiments together; their teamwork is what truly what gave rise to the discovery of latent heat. So although Joseph Black did not directly invent the steam engine, his discoveries in the lab is what made the industrial invention possible (Cooper, 1999). A

many access to tailor the molecule suitably for wide range of applications in medicinal,[1] synthetic,[2] and applied chemistry.[3] The fluorine has the special topic of interest among the chemists as its introduction into the organic molecules leads to a dramatic changes in their physical and chemical properties.[4] The recent activities show a remarkable growth in fluorine chemistry as the chemists practiced to do polishing the organic molecules with fluorine to improve their properties, leading

For the last 5 decades, electronics coupled with organic chemistry has been an area of great research interest, especially in physics and chemistry. Until a few years ago, this topic was thought to have no practical approach and was believed to be just research-oriented. Modification of chemical structures so that they can in a way enhance the properties of these when used for electronic applications- especially as a thin film has gained major impetus. It was always thought that organics would soon

1. 150 ml of boiled water was poured into each of the three beakers labeled A, B, C. 2. Five tea bags were soaked for the time given by the manufacturer (two minutes) , in beaker A (Control). The teabags were immediately removed after the time elapsed. 3. Another five tea bags were soaked for fifteen seconds in beaker B and then removed. The same teabags were then placed into beaker C for two minutes. They were removed after the time elapsed. 4. The solutions were allowed to cool to room temperature

Because of limitless industrial importance of PUs, hence need to study diisocyanate chemistry briefly and understand the properties and their reactivity. Mainly the isocynates are highly reactive and allow to forming urethane groups without any by-products formation. This isocyanates contains two or more –NCO functional groups for one molecule

Chemistry is used in the study of geology to determine how the earth is affected by humans or changes in the atmosphere, and it is also used to determine the exact compositions of different soils or rocks. Geologists use chemistry to see exactly how the Earth changes underneath us, they use it to determine changes in the composition of the soil in areas affected by pollution, or they can detect certain deposits of resources in the ground. They examine the chemistry of soil and rock of different areas

Exp. 10 - The Chemistry of Natural Waters David Graves 11/10/15 CHEM 111 Section 104 TA: Lai Shi Group Members: Jasmine Graves, Brad Hensler, Peter Hoholick Introduction Experiment 10: The Chemistry of Natural Waters investigates the topic known as water hardness. Hardness is a chemical property of water that evaluates the concentration of dissolved divalent cations such as Ca and Mg, which happen to be the two ions that are tested for in the experiment. Hardness can be measured
