Sources of perchlorate Perchlorate is a chemical that occurs naturally, although it may as well be man-made. In addition, perchlorate can also be found in some fertilizers and in bleach. It has found wide application in the manufacture of fireworks, flares, rocket fuel, and explosives1. Many of the sites where perchlorate can be found occurring […]

Abstract Human activities continue to threaten the purity of water by releasing pollutants from industries and domestic water usage. When phosphates in aqueous solutions gain access into water bodies, they lead to the abnormal growth of algae, which reduces the concentration of dissolved oxygen. Therefore, phosphates in aqueous solutions must be reduced before the solutions […]

Introduction Plastics are found everywhere and have many uses. However, there are some limitations to the use of plastics and one of these is that they cannot withstand a temperature way above 200°C. Plastics that can withstand high temperature are applied with so-called aromatic base. This kind of plastic is exposed to condensation during manufacturing […]

Introduction: Chloramine As an Alternative Among all the essentials that a human being cannot possibly live without, water takes the first place after oxygen – once deprived of the necessary amount ofH2O and disposed to a long-term drought, a human body stops functioning and starts to disintegrate into nothingness. Luckily enough, water reserves on the […]

Pierre Curie was fascinated by the ability of uranium to blacken photographic plates after months of exposure. At the time, the phenomenon was hard to explain as it was in contrary to the scientific fact that energy can neither be created, nor destroyed. When his wife, Marie Curie, needed support for her doctoral thesis, Pierre […]

Introduction The extraction of lubricating oils from crude oil is a multistep procedure as mentioned earlier in the paper (Speight, 1980, p.71). The reason behind this is the inability to achieve constant liquid phases as certain temperatures. For that matter, single stage extraction of lubricating oils is difficult. In the ancient times, the extraction process […]

Introduction A lubricant’s de-waxing process involves removal of paraffinic hydrocarbons so as to improve the pour point of the feed stock. The pour point of oil is the lowest temperature in which oil can flow, pour or move when refrigerated or cooled without disruption under certain fixed conditions. De-waxing produces high yields of products of […]

Introduction The following is a discussion on the topic flammable and combustible liquids, how they burn and take various aspects. This discussion is particularly interesting to anyone who wants to gain an understanding on the element of fire. This research paper will take a summary approach where it shall provide a summary of information acquired […]

Oxygen is a vital gas that occupies up to twenty one percent of the earth’s atmosphere. Animals and human beings require oxygen for their survival while it is the excreted by plants as an end product of photosynthesis. As a matter of fact, oxygen is present almost everywhere forming two thirds of the body mass […]

Introduction Amphetamines are analogues of β-phenethylamine and have a stimulant effect on the central nervous system. Prolonged use results in addiction and dependence. Changes in the structural framework of the basic amphetamine nucleus results in different forms of amphetamines. Absence of modifications on the aromatic nucleus results in a potent subgroup of amphetamines such as […]

Introduction Aluminium is comparatively a flexible, tough, and lightweight metal. It is silvery in colour, is non-magnetic and doesn’t catch fire easily. Aluminium is also an excellent reflector of radiance and infrared rays. It belongs to the boron family and its chemical symbol is ‘Al’, with atomic number 13. If we talk about the abundance […]

Introduction Chemistry involves more than the mere fact that that it entails the making of new combinations of chemical elements. It makes new combinations of industries and brings together different countries besides the chemical elements. It brings international competition, which results into the development of international cooperation. Chemistry improves everyday life of millions of people […]

An American writer decides to take a test to determine the level of foreign substances in his body. Laboratory test results indicate that some substances, some of which are used to reduce flammability of materials, are present in his blood. The level of concentration of these compounds is many times higher than the level that […]

Enzymes are described as biological proteins which accelerate the rate of reaction of a chemical substance, while inhibitors are elements which reduce the speed of catalyzed reaction of enzyme through connecting into the enzyme and jamming the reaction of enzyme (Hunter, 2009, p. 41). Enzymes function in the human body through reducing the activation energy […]

This research revolves around the production and processing of gold as one of the most precious metals in the world. Gold was never actually formed and it is a natural element that can only be obtained through mining. In that case gold is itself a highly valuable mineral categorized among other precious metals such as […]

There have been many radical changes in concepts of science of the 17th century where new scientific concepts and laws replaced old ones most notably chemical revolution. One of the revolutionary conceptual changes occurred when phlogiston theory of Stahl was replaced by the oxygen theory of Lavoisier. According to the phlogiston theory popular in the […]

Chemical revolution involved the conceptual change which followed the development of the oxygen theory by Lavoisier that replaced the then popular phlogiston theory. Several factors contributed to this revolution including Priestley and Cavendish experiments, which proved that air is a mixture of gases rather than a single element as the then conventional understanding. The improvement […]
