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.

[Chemistry in anatomy]

I am a Junior in High School and taking a College level Anatomy class. We are on our chemistry unit and i am completly lost. My anatomy book is very vuege on the subject and the packet we need to complete isnt. I need help extremly bad. The packet is 18 pages front and back dealing with everything from basic lewis dot struchutes all the way to DNA and ATP. If anyone is interested in helping me please reply.

my mate says if he ate a paper clip it would disolve with in ur stomach is this true

[Melissa Fish]

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.

Help! can anyone help How many grams of CaF2(FM=78) would form when 33 ml of 0.41 M NaF react with excess CaCl2 according to the equation 2 Naf+CaCl--------CaF2+2NaCl Excess problems in molarity are screwing me up right now can you help. Any clues thanks.

this is confusing stuff =o

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??
