100% times the actual yield divided by theoretical yield.
- 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...
- 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...
- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
- 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?
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
Method of Initial Rates
Method of determining the rate-law expression by carrying out a reaction with different initial concentrations and analyzing the resultant changes in initial rates.
A process for the industrial production of nitrogen oxide and nitric acid from ammonia and oxygen.
The number (6.022x10^23) of atoms, molecules or particles found in exactly 1 mole of substance.
Water containing Fe3+, Ca2+, and Mg2+ ions, which forms precipates with soap.
An atomic emission or absorption spectrum.
An inhibitor, a catalyst that decreases the rate of reaction.
A thin partition between two solutions through which certain molecules can pass but others cannot.
An orbit resulting from overlap and mixing of atomic orbitals on different atoms. An MO belongs to the molecule as a whole.
Binding Energy (nuclear binding energy)
The energy equivalent (E = mc^2) of the mass deficiency of an atom. where: E = is the energy in joules, m is the mass in kilograms, and c is the speed of light in m/s^2
High energy electromagnetic radiation. A highly penetrating type of nuclear radiation similar to x-ray radiation, except that it comes from within the nucleus of an atom and has a higher energy. Energywise, very similar to cosmic ray except that cosmic rays originate from outer space.
The amount of heat required to raise the temperature of one gram of substance one degree Celsius.
The absorption of heat by a system as the process occurs.
Outer Orbital Complex
Valence bond designation for a complex in which the metal ion utilizes d orbitals in the outermost (occupied) shell in hybridization.
Standard Electrode Potential
By convention, potential, Eo, of a half-reaction as a reduction relative to the standard hydrogen electrode when all species are present at unit activity.
Reactions in which two compounds react to form two new compounds, with no changes in oxidation number. Reactions in which the ions of two compounds exchange partners.
Coordinate Covalent Bond
A covalent bond in which both shared electrons are donated by the same atom, a bond between a Lewis base and a Lewis acid.
The smallest particle of an element or compound capable of a stable, independent existence.
A heterogeneous mixture in which solute-like particles settle out of solvent-like phase some time after their introduction.
Isomers that differ only in the way that atoms are oriented in space, consist of geometrical and optical isomers.
