The amount of energy necessary to break one mole of bonds of a given kind (in gas phase).The amount of energy necessary to break one mole of bonds in a substance, dissociating the sustance in the gaseous state into atoms of its elements in the gaseous state.
- 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.
A molecular orbital higher in energy than any of the atomic orbitals from which it is derived, lends instability to a molecule or ion when populated with electrons, denoted with a star (*) superscript or symbol.
Hydrated sulfates of the general formula M+M3+(SO4)2.12H2).
The buildup of a product of oxidation or a reduction of an electrode, preventing further reaction.
An instrument that measures the charge-to-mass ratio of charged particles.
Two methyl groups of the same carbon atom.
A noncrystalline solid with no well-defined ordered structure.
Absorption of high energy radiation by a substance and subsequent emission of visible light.
Any of three oily, colorless, water-insoluble, flammable, toxic, isomeric liquids, C8H10, of the benzene series, obtained mostly from coal tar: used chiefly in the manufacture of dyes.
A relatively large energy separation between an insulator's highest filled electron energy band and the next higher energy vacant band. Beginning in the fourth energy level, a set of seven degenerate orbitals per energy level, higher in energy than s, p, and d orbitals of the same energy level.
A group of atoms that represents a potential reaction site in an organic compound.
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
Law of Partial Pressures (Dalton's Law)
The total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
Potential difference, Ecell, between oxidation and reduction half-cells under nonstandard conditions.
A listing of metals (and hydrogen) in order of decreasing activity.
Having the same electronic configurations.
Covalent bond in which electron density is symmetrically distributed.
A thermodynamic state or property that measures the degree of disorder or randomness of a system.
A physical state of matter which exists at extremely high temperatures in which all molecules are dissociated and most atoms are ionized.
