Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.
- 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...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
Isomers of crystalline complexes that differ in whether water is present inside or outside the coordination sphere.
Descibes the quantitative (mass) relationships among elements in compounds.
Potential difference between two electrodes, a measure of the chemical potential for a redox reaction to occur.
A soap-like emulsifer that contains a sulfate, SO3 or a phosphate group instead of a carboxylate group.
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.
Unsaturated hydrocarbons that contain one or more carbon-carbon double bonds.
A binary compound of hydrogen.
The quantity of product formed by the interaction of two or more substances, generally expressed as a percentage of the quantity obtained to that theoretically obtainable.
The rotation of plane polarized light by one of a pair of optical isomers.
Rods of materials such as cadmium or boron steel that act as neutron obsorbers (not merely moderaters) used in nuclear reactors to control neutron fluxes and therfore rates of fission.
A term used to describe molecules and polyatomic ions that have one atom in the center and six atoms at the corners of a octahedron.
A highly reactive chemical species carrying no charge and having a single unpaired electron in an orbital.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
Region or volume in space in which the probability of finding electrons is highest.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
An organic compound containing a sugar or sugars.
Heat of Vaporization
The amount of heat required to vaporize one gram of a liquid at its boiling point with no change in temperature. Usually expressed in J/g. The molar heat of vaporization is the amount of heat required to vaporize one mole of liquid at its boiling point with no change in temperature and usually expressed ion kJ/mol.
The arrangement of atoms (not lone pairs of electrons) about the central atom of a polyatomic ion.
A gas or mixture of gases having, in a container an absolute pressure exceeding 40 psi at 21.1°C (70°F)
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
