A Ligand that exerts a weak crystal or ligand field and ge- nerally forms high spin complexes with metals.
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
The number of moles of a component of a mixture divided by the total number of moles in the mixture.
Le Chatelier's Principle
States that a system at equilibrium, or striving to attain equilibrium, responds in such a way as to counteract any stress placed upon it.
If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
A neutral subatomic particle having a mass of 1.0087 amu.
The temperature above which a gas cannot be liquefied, the temperature above which a substance cannot exhibit distinct gas and liquid phases.
Reaction of a substance with water.
Unit of electrical current, one ampere equals one coulomb per second.
Placing a thin layer of zinc on a ferrous material to protect the underlying surface from corrosion.
Substances consisting largely of hydrocarbons, derived from decay of organic materials under geological conditions of high pressure and temperature (metamorphism) include coal, petroleum, natural gas, peat and oil shale. For further information see Fuel Chemistry
Reactions that do not go to completion and occur in both the forward and reverse direction.
A solution that obeys Raoult's Law exactly.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
Noble Gases (Rare Gases)
Elements of the periodic Group 0, also called rare gases, formerly called inert gases, He,Ne,Ar, Kr, Xe, Rn.
A device used to measure the densities of liquids and solutions.
A class of enzymes found in bacteria within root nodules in some plants, which catalyze reactions by which N2 molecules from the air are converted to ammonia.
A very slightly soluble compound.
Colloidal suspension of a gas in a liquid.
A term used to describe molecules and polyatomic ions that have one atom in the center and four atoms at the corners of a square.
A gas formed by boiling or evaporating a liquid.
Any state other than the ground state of an atom or molecule.
