Hydrogen Term Papers Samples For Students

Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Since ...

Hydrogen cyanide, abbreviated AC by military, is an inorganic compound that is colorless and is extremely poisonous liquid. It has a boiling point (26°C) that is slightly more than the room temperature. The molecule of hydrogen cyanide is linear and has a triple bond that joins the carbon atom and nitrogen atom together. Hydrogen cyanide has a weak acidic mature with a pKa of 9.2 and is partially ionizes in a solution of water giving cyanide anion. A hydrogen cyanide solution in water, is referred to as hydrocyanic acid while the hydrogen cyanide salts are referred to as cyanides. Hydrogen cyanide is mainly ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Travelling to another planet is referred to interplanetary spaceflight. The term is usually used when travelling to a planet within the same planetary system (Fisher 1). The human race has made tremendous strides in space exploration. Man has made it to the moon and back, which was a great achievement for science as well as the human race. Man may not have stepped onto another planet yet, but significant achievements have been made in interplanetary exploration. There have been explorations using probes that have flown by every planet in the solar system. The New Horizons recently flew by the ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant.
In piping systems, however, there are several water quality factors working singly ...

The discovery of DNA as the genetic material was one of the landmark events in the field of biology. By confirming DNA as the genetic material scientists made a huge leap that has advanced the cause of medical science to a great degree. While discussing the discovery of DNA as the genetic material, we mostly speak of Friedrich Miescher (1871), the man who discovered DNA. After the discovery of DNA a significant number of studies were conducted that proved DNA as the genetic material. Then Griffith, (1928) conducted studies on bacterial transformation and indicated that genetic information can be transferred from one ...
