The energy change accompanying the hydration of a mole of gase and ions.
- 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...
- 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?
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
One faraday of electricity corresponds to the charge on 6.022 x 1023 electrons, or 96,487.301 coulombs.
Any of a number of lines corresponding to definite wavelengths of an atomic emission or absorption spectrum, represents the energy difference between two energy levels.
A cluster of atoms in a ferromagnetic substance, all of which align in the same direction in the presence of an external magnetic field.
The rates of effusion of gases are inversely proportional to the square roots of their molecular weights or densities.
Band of Stability
Band containing nonradioactive nuclides in a plot of number of neutrons versus atomic number.
A plant extract that has a distinctive odour or flavour.
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
Integral number of protons in the nucleus, defines the identity of element.
Refers to an optically active substance that rotates the plane of plane polarized light clockwise, also called dextro.
The number (6.022x10^23) of atoms, molecules or particles found in exactly 1 mole of substance.
A mixture which has uniform composition and properties throughout.
Hydrogen-Oxygen Fuel Cell
Fuel cell in which hydrogen is the fuel (reducing agent) and oxygen is the oxidizing agent.
Weak Field Ligand
A Ligand that exerts a weak crystal or ligand field and ge- nerally forms high spin complexes with metals.
An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.
The very small, very dense, positively charged center of an atom containing protons and neutrons, as well as other subatomic particles.
Law of Combining Volumes (Gay-Lussac's Law)
At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.
The attractive forces that hold atoms together in elements or compounds.
Substances that flow freely, gases and liquids.
A noncrystalline solid with no well-defined ordered structure.
