or, to put it another way, "chemistry carried out with the primary object of investigating the workings of nature is what we now call physical chemistry" (Laidler, 5). This has made the distinction between physics and chemistry at this frontier very difficult to define. This fuzzy distinction is also one of the things that makes the discipline of physical chemistry so interesting -- it cannot deny the complete interweaving of scientific disciplines.
Physics and chemistry lay out the foundation and explain the mechanisms of all other sciences, and the field of physical chemistry is the closest unification of these two sciences. All biological and astronomical processes only occur because of reactions and interactions at the molecular and atomic level, and physical chemistry attempts to explain these underlying principles (Laidler, 9). Though the nature of energy and matter is still not fully understood, physical chemistry is approaching better and better explanations of the way the universe is constructed.
One of the most interesting disciplines within physical chemistry is the field of quantum mechanics. This is an attempt to explain the way subatomic particles, particularly electrons, move, and was first proposed following the development of quantum chemistry in 1924 (Laidler, 330). Niels Bohr's theory of the atom was in large part responsible for the development of quantum mechanics; the Bohr atomic model was one of the earliest and best explanations of a physical construction of the atomic that explained the various chemical properties noticed in different elements and molecules, including the way atoms...
They are compounds that have carbon, hydrogen and oxygen. There are 3 forms of carbohydrates. First are the monosaccharides which are simple sugars. They have simple structures in the ration of 1:2:1. They usually contain 5-6 atoms of carbon arranged in a 5-6 member ring. Oligosaccharides are monosaccharides which are combined in short strings that are linked together through dehydration synthesis. Sucrose is one of the oligosaccharides. It is
The entire unit is known as a photosytem and in green plants, one finds two of these systems, photosystem I and photosystem II, both of which are involved in the light reactions of photosynthesis. Light energy absorbed by these pigments of the antenna complex is "passed to the reaction center chlorophyll molecules from which it passes along an electron-transport chain" (Blankenship, 215). Photosystems II contains a kind of chlorophyll a
Chemistry Based on the fact that our class focuses on atoms, atomic structure, chemical bonds, nuclear chemistry (radioactivity, nuclear equation, half life, radio isotopes, artificial transmutation, etc.), this article review aims to provide a summary of a related story named "IBM Scientists First to Image the 'Anatomy' of a Molecule; Imaging Individual Atoms Within A Molecule Has Been A Long-standing Goal of Surface Microscopy" by the IBM press team in the
Chemistry and Recreational Drugs The objective of this study is to examine chemistry as it relates to recreational drugs. Toward this end, this study will review literature in this area of inquiry and report on the same. Recreational drugs refer to drugs such as marijuana, methamphetamine, ecstasy, cocaine, and other such drugs. The chemistry of each of these recreational drugs is unique and each cause specific effects to the individual taking these
Chemistry The Many Dimension of Red Red is one of the oldest colors known to humans. It is a color that carries with it significant emotional meanings. Red occurs in nature on Earth and in the cosmos. It is a dynamic color affecting people and animals. The paper will explore the history of the color red with regard to its chemical properties, natural history, and cultural significance. The study of color proves
Chemistry The Prosperous Autobiography of Phosphorus Greetings humans, this message is from your friend, Phosphorus. That's Phosphorus with a "-us" and not an "-ous" and it is often misspelled. I am an element, not an adjective. You may not be unaware of the special connection you have with me, but it exists nonetheless. For you see, I, Phosphorus, am "an essential component of living systems and is found in nervous tissue, bones
