When straining your body through physical activity, Gatorade keeps your body hydrated, keeps the electrolytes balanced, and replenishes carbohydrates. However, Gatorade has several negative effects as well, which can be extremely toxic to the body. This very popular drink has both positive and negative effects …
Human understanding to the world of the minuscule atoms had changed over the passing of time. Several scientist physicists had almost devoted their entire life in order to achieve a better view to the building blocks of matter. Numerous persons had attained to be acknowledged …
Introduction Chemical reactions are a part of our daily lives, from rusting metal to making bread to leaves changing colour in the fall. A chemical reaction is the process that occurs when two or more substances combine to produce a chemical change. When a chemical …
Application of Fluorescence Spectroscopy in Chemical Oceanography: Tracing Colored Dissolved Organic Matter (CDOM) Erika Mae A. Espejo 3rd year, BS Chemistry, University of the Philippines, Diliman Abstract Dissolved organic matter (DOM), the fraction passing through a 0. 45 µm membrane filter, is considered poorly understood …
The Development of the Periodic Table Although Dimmit Mendel is often considered the ‘father’ of the periodic table, the work of many scientists contributed to its present form. Between 1817-1829, Johann Doberman began to group elements with similar properties in to groups of three or …
SMART Materials A SMART material is a material that is affected by outside influence. Polymorph * Type of thermoplastic (can be reshaped many times). * Normally supplied in form of granules or small plastic beads. * Low fusing temperature of around 60°C. This means it …
Introduction: The term fabrication applies to the cutting, bending, forming, and welding of Individual pipe components to each other and their subsequent heat treatment and nondestructive examination (N DE) to form a unit (piping subassembly) for installation. The term installation refers to the physical placement …
Acidity in soils comes from H+ and Al3+ ions in the soil solution and sorbed to soil surfaces. While pH is the measure of H+ in solution, Al3+ is important in acid soils because between pH 4 and 6, Al3+ reacts with water (H2O) forming …
In the last forty years, Uranium has become one of the worlds most important energy minerals. Primarily, Uranium produced in Australia has used for the sole production of electricity. However a small proportion of the Uranium mined is for important medical isotopes. It is for …
Introduction and overview This Essay would tend to analyse and define Renewable Energy as a whole.It would also list and discuss types/main forms of renewable energy and its commercialization to members of the public. The essay would aim to discuss economic importance of Renewable energy,new …
Introduction Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab, we will make them be a prime example of osmosis, which is a transport mechanism. In this lab the problem being tested …

Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
