Chemistry: At Least Half of Everything
26th June 2007 Author: anthony amerson It has been often said and many times proven that nothing exists or can be explained without mathematics and chemistry. Chemistry is the essence of all things and mathematics is the universal language utilized to explain this essence. Chemistry is the science that studies molecules, crystals, metals, and non-metals and it is concerned with the composition, transformations and interactions of all materials found in everyday life. Chemistry is called the ’central’ science. This is because it is the link between other natural sciences such as biology, geology, astronomy and physics. Chemistry involves the interaction of matter. It can be used to describe interactions of matter to matter, or of matter to energy. Chemists use reaction equations to explain these interactions. For instance, the popular reaction equation for the formation of water from hydrogen and oxygen interacting is as follows: 2 H2 + O2 ? 2 H2O There are many sub-disciplines of chemistry. The chemistry taught in high school and at the beginning of collegiate studies is called general chemistry and is meant to pertain to the fundamental concepts of this huge field. Modern chemistry stems from the ancient alchemists. For thousands and thousands of years, these primitive chemists attempted to crack the codes of life, and all of its components. Today chemistry has grown into a monster of explanation, creating the fields of forensic sciences and genetics. Criminologists, physicians, fuel and power companies and processed food manufacturers all are in total debt to the field of chemistry. In actuality, anything and everything that you can experience with any of your senses, solitary or in combination, can only be explained in terms of chemistry. As a subject of study, chemistry presents not only the most versatile and exciting potential, but perhaps the most perplexing and difficult as well. Chemistry is everything. It is life and death; it is everything in between. Written by Anthony Amerson. Find more information on href=http://www.justchromatogr aphy.com/>chromatography here.

my mate says if he ate a paper clip it would disolve with in ur stomach is this true
|
||||
|
Yes, the strength of the hydrochloric acid in your stomach would be strong enough to dissolve a paperclip. But this would only happen if the paperclip stayed in your stomach long enough I think.

Hi, I'm working on a lab and I need to calculate the concentration of the FeSCN 2+ complex. The solution concentration of FE 3+ is 0.2 M and SCN is 0.0025M. 0.005L of SCN, 0.005L of Fe were added to a 25 mL flask and then diluted to the mark so the amount in the flask equalled 25 ml. Can anyone tell me how to find the concentration of the FeSCN complex??
