Chemical Reaction College Essays Samples For Students

Stars begin their lives from molecular clouds or nebula of gases and dust. These gases and dusts exert forces to each other that make them want to move farther away from each other while at the same time there is gravity that attracts them together into a small space within the nebula. The chemistry which starts the star’s life begins when gravity starts winning in the war between the two aforementioned opposing forces. As gravity pulls the dust and clouds together it begins to accumulate mass and a swirling motion typical to a spinning disc. At its center are dusts (NH3, ...

THE SCOPES TRIAL

The scopes trial is also famously known as the scopes monkey trial and was a trial which involved the state of Tennessee against John Thomas Scopes. The charge against scopes was teaching evolution. Apparently back in 1925 it was illegal to teach anything about evolution in schools that were funded by the state. Back then people believed in the divinity of the bible. Anything in the bible was considered truth that was incontestable by any human being irrespective of the evidence at hand. Teaching evolution was tantamount to blasphemy against morally accepted truths by the people. The Buttler act made ...

Everyone loves the food at the dining table to be appealing to their senses besides their taste buds through attractive colors and flavors. For instance, one cannot imagine a loaf of bread without its trademark golden brown crust. How do foods get their unique color and aroma? A series of reactions known as Maillard reactions produce countless chemical compounds that give foods like bread, chocolates, potato chips and roasted meat their unique colors (Copeland, 2016). These reactions take place at high temperatures of around 130℃ when raw food items are baked, roasted or fried. This explains why boiled, steam-cooked ...

Surgical Anesthesia

Pharmacology and Indications
Licocaine
Licocaine is a type of medication used with an aim of numbing tissues and nerves within a given area of the body, which provides that anesthetic effect for the body. The most popular brand names for this particular drug are xylocaine and lignocaine. Some of the common effects associated with this particular medication include drowsiness, muscle twitching, nausea, and confusion (1). The severity of the side effects depends wholly on a patient’s reaction to the chemical composition of the drug. Regarding its mode of action, licocaine works by blocking the voltage-gated Na+ channels, which ...

Chemical Weathering

Chemical weathering in the mid-latitudes is the process where rocks are weakened and disintegrated by chemical reactions that occur in the soil. Some of the chemical reactions that cause chemical weathering are oxidation, carbonation, and hydrolysis. These processes are involved in either forming or destroying minerals and therefore altering the nature of the mineral composition of the rocks. The process of chemical weathering on rocks characterizes the second stage of rock disintegration. The first process occurs during physical weathering and it involves disintegrating rocks into small pieces which are further broken into smaller pieces by chemical weathering. The most ...

Introduction

The European Union is one of the most united bodies in the world today. EU epitomizes unity and centres in the common good of its members. Obviously, the business interrelation and other working domains of the Union has gone a long way to garner success for its members. As a united body, the EU represents the most powerful force in the world that cannot be thwarted by external powers. Although this union can be labelled a success by all and sundry but it fails in some aspects especially in issues relating to the environment but not in toto. This ...

Discussion 1: Public Speaking

I definitely agree with the statement: Knowing the background, interests, and expectations of your audience significantly increases the effectiveness of your speech. All this information will help to find the right approach, to make the speech interesting exactly for these people. It is important to use the references, which will be familiar to audience. Sometimes it might be a good idea to use jokes to lighten up the atmosphere. But if the audience doesn’t appreciate your sense of humor or they will be somehow offended by it then it will just make the matters worse. You should absolutely ...

Certain elements involved in the geochemical and biogeochemical cycling are of great concern due to their limited availability both naturally or through industrial manufacture of the compounds involved in the cycles. Some of the processes involved are chemical reactions with other elements or substances. Some of these reactions are irreversible chemical reactions. This implies once the reaction has taken place, the elements are removed from natural cycle and they cannot be replaced again. As such, the more the cases of irreversible reactions, the greater the rate of reduction of these elements from the environment. Ultimately, there could be less ...

How Enzymes Act As Protein Catalysts in Biochemical Processes
Catalysis refers to the speeding up of a chemical reaction by a catalyst. A catalyst is a substance that accelerates a chemical reaction but does not undergo a permanent chemical change in the process. Enzymes are catalysts whose building blocks are amino acids: they are proteins. Enzymes also exhibit a defined three-dimensional structure. In addition, they have a cleft on their surface called active site. The active site is the region where substrate interactions take place. Enzymes play important roles in fructose metabolism. The first step of fructose metabolism in the liver is the phosphorylation of ...

Introduction

Q1 . The fundamental requirement for a living cell to sustain itself are a carbon source, an energy source, an electron donor, an electron acceptor and elemental nutrients(N,P, S, Mg,) etc. Explain how each of these fundamental requirements are needed by the living cell to function. Explain how the cell can maintain its own internal biological processes without being in equilibrium with the external environment.
The living cells can function within a constricted range of such conditions such as nutrient availability, pH, ion, temperature, etc. The cell must coordinate different chemical reactions and consolidate many different molecules into definite structures, ...

Mechanical Engineering is a branch in the field of science that encompasses a large field of designing and manufacturing small individual parts and devices, as well as large systems. The branch is at the heart of moving products from ideas to the marketplace. The branch of engineering involves creating products that will withstand different forces and the thermal environment to ensure they function properly. It entails the design, manufacturing, analysis and maintenance of mechanical systems using principles of materials science and physics. Mechanical engineering is not only concerned about functionality of products but also about aesthetics too. In its broad application ...

Introduction

Biochemistry is the study of composition, structure and the chemical reactions taking place in living organisms. Dental biochemistry is the study of the composition, structure and chemical reactions taking place in teeth (Chary & Sharma 2004). The teeth form the sensitive part of the human being. The teeth enhance the looks of a human being and it is also for eating. When the dental formula of a human being is correct, the confidence to talk improves unlike when the dental formula is not proper. When care is not taken, the teeth will contact diseases. There are various causes of the diseases in ...

Enzymes are sometimes referred to as biochemistry workhorses because they are utilized by many scientists to speed up a number of chemical reactions. Enzymes are proteins that speed up, or in other words catalyze, specific biological and chemical reactions by increasing the rates of reaction by more than a million factors. An example of these enzymes is Pectinase, which is the enzyme that catalyzes pectin breakdown. Pectin is a part of the cell wall of fruits like tomatoes, mangoes, oranges and apples. Pectins are large colloidal molecules and they are responsible for holding or determining the amount of dispersed particles in extracted ...
