Introduction.

When teaching science, instructors use a specialized language that has many dissimilarities from the language that students generally use throughout the day (O’Toole, 2003). Each different occasion for language has a set of intrinsic purposes, values and characteristics, and the purpose of these different traits is to demonstrate the unique properties of that category of language. For example, in scientific language, there is an emphasis on precision in diction, as well as conciseness and clarity. No matter what the language is, writers hope to achieve a style that is comprehensible to its readers while remaining true to the aims of the ...

Introduction

Ozone layer is naturally evolved a layer made up of atomic oxygen with molecular oxygen and covers a big area in stratosphere. The distinct function of the ozone layer is to absorb ultraviolet wavelengths coming from the solar waves. The collision of ozone occurs because of several other atmospheric molecules and UV radiations (Tabin, 2008).

O3+ UV >>> O2 + O O3 + O >>> 2O2

The maintenance of the ozone layer is very necessary as through absorbing the solar radiation Ozone establishes ...

Introduction

Spectrophotometry refers to a method that is employed in the determination of the amount of light that is absorbed by a chemical substance. In chemistry, the term spectrophotometry refers to the determination of the reflection or transmission characteristics quantitatively material through a function of wavelength (NIST, 2012). The spectrophotometry analysis is carried out through the light intensity determination as a beam of light passes through a tube containing the sample solution. The process of analyzing solution concentration using spectrophotometer utilizes the fact that light possesses a dual nature. This is where the light may exist either as particle or as a wave (Keller, 2003). Basically, ...

Physical science concept represents knowledge which has resulted after research and experiments on different scientific theories. During the development of such knowledge, measurements are made. Challenges in measurement are often related to the efficacy of the measuring tools being used. Challenges in measurement are as a result of lack of a direct method of measuring. In astronomy, the scientists face a number of challenges such as measuring the distance between stars, the mass, and components making up the stars. This ...

Lloyd Augustus Hall

Lloyd Augustus Hall’s contribution to science largely involves food preservation. Lloyd’s interest in food chemistry, a new area of chemistry, started while working at Boher Chemical Laboratory. Before his inventions, table salt (sodium chloride) was used as the major food preservative especially in preserving meat (Wilson and Jane, 34). However, table salt was not effective enough, as meat could only be preserved in a short period using this technique. Following various experiments, Lloyd came up with “flash-drying” technique as an alternative to table salt preservation. The technique involved a combination of sodium nitrate crystals and nitrite and sodium chloride, which ...

There have been few people that have matched up to the scientific know how of the Curie family. The Curie family has received the most Nobel Prizes in history. Marie Curie, the matriarch of the family, was the first women to win a Nobel Prize and is the only person to win a Nobel Prize in two separate fields of science. Her accomplishments include describing the theory of “radioactivity” as well as coining the term; she also discovered to elements, polonium and radium. The theories of radioactivity helped during World War I where she assisted on the front lines in creating ...

Nicolas Leblanc, in 1791, gave the world a chemical compound which revolutionized food products, Sodium Bicarbonate. More commonly known as baking soda, this base has become an integral substance found in almost every household. Leblanc, a surgeon and private physician, was striving to make ends meet for his family when he heard about the prize offered by the French Academy of Science to anybody who can develop a process for producing soda ash from salt. The prize finally went to Leblanc, who had come up with the Leblanc process, which developed baking soda from seas salt and sulfuric acid. The unfortunate part ...

In chemistry, a hypothesis is a means to help explain phenomena. It is an idea that might explain why something happens. In contrast a theory in chemistry refers to testing this hypothesis by trying to determine what is true about a phenomena. A hypothesis is used to test why something happens. This is used to help develop the theory. The theory is based upon the truths discovered by testing the hypothesis. A law includes the entire collection of observations. Laws explain things but does not describe them differentiating them from a theory (Lastrucci, 1963) . The scientific process is a natural progression between these different ...

Introduction

The founder of the Nobel price, Alfred Nobel was a distinguished scientist and investor. He owned a variety of firms that produced goods ranging from weapons to edibles.

Lehn defines the concept of Supramolecular chemistry as 'chemistry beyond the molecule'; chemistry of the intermolecular bond that includes the functions and structures of the entities resulting from the bonding between multiple chemical species. According to Vogtle and Alfter (1991), supramolecular chemistry, contrary to molecular chemistry, is based on intermolecular bonding or interactions, while the later is predominantly based on the covalent bonding of atoms. In other words, supramolecular chemistry deals with the bonding between two or more building blocks that are bound together by means of intermolecular bonds. The aforesaid concept bears on the organized entities of ...

Lab Memo: Cyclic Voltammetry: Identification and Quantification of Unknown Concentrations of Substituted Benzoquinones

1.Introduction

Cyclic Voltammetry (CV) measures the redox behavior of electeroactive species and is useful for a whole spectrum of molecules in inorganic chemistry, biochemistry, electrochemisty as well as organic chemistry. A voltammogram is the readout of the energy scan which can be used to determine unknown concentrations. Voltammogram wave shape is very different than in spectrometry and chromatography. The wave is triangular in shape because the y-axis describes the shift in the potential which is the voltage of a working electrode versus a reference electrode. The x axis describes duration in seconds. (Kissinger and Heineman).

Two samples each with an unknown concentration of benzoquinones were analyzed with the instrument, BASi Epsilon-EC.

The Origins of Life

The origin of life has long been a subject of much scientific debate and scientists have put forward various theories to explain how life may have begun. One such theory was advanced by Miller Urey in 1953(Moritz, 2010). Urey carried out an experiment which he assumed simulated the conditions of Primitive Earth. This experiment was referred to as ‘pre-biotic soup’ which showed how organic molecules like amino acids were formed from mixtures of water, ammonia, hydrogen, and ammonia. This experiment is controversial in that scientists are skeptical about the presence of a reducing atmosphere though several experiments have suggested that ...

Introduction

At ambient temperature and pressure, mercury (the elemental mercury) is a metal in form of heavy silvery-white liquid. It exists in three oxidation states: mercuric Hg+2, metallic Hg, and mercuros Hg2 +2. Organic and Inorganic compounds are formed by mercuric and mercuros states. The mercuros state is unstable under environmental conditions. Mercury exists in water, sediment, soil and biota only in inorganic mercuric salts and organomercurics. In the Cold Vapour analysis, mercury from the digest sample is reduced with either SnCl2 or NaBH4 and then measured with a conventional cold vapour flameless atomic absorption spectrometry. The whole system is ...
