Absorption of a K shell (n=1) electron by a proton as it is converted to a neutron.
- 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...
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
An oxidizing or reducing agent, who's mass gains (oxidizing agents) or loses (reducing agents) 6.022 x 1023 electrons in a redox reaction.
The mass of an acid or base that furnishes or reacts with 6.022 x 1023 H3O+ or OH- ions.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
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.
The pentosan occurring in woody tissue that hydrolyzes to xylose: used as a source of furfural.
Corrects standard electrode potentials for nonstandard conditions.
The solvent-like phase in a colloid.
A series of very closely spaced, nearly continuous molecular orbitals that belong to the crystal as a whole.
Equilibria involving only one species in a single phase. For example, all gases, all liquids or all solids.
Any of a group of dyes having a molecular structure related to that of xanthene in which the aromatic (C6H4) groups are the chromophore.
Energy that matter possesses by virtue of its position, condition or composition.
A thermometer used for accurate measurement of very small changes in temperature.
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.
Protection of a metal (making ir a cathode) against corrosion by attaching it to a sacrifical anode of a more easily oxidized metal.
Half-cells in which the oxidized and reduced forms of a species are present at unit activity, 1.0M solutions of dissolved ions, 1.0atm partial pressure of gases, and pure solids and liquids.
Mixing of metal with other substances (usually other metals) to modify its properties.
It is the force in dynes acting along the surface of the liquid 1cm in length and perpendicular to it.
Solubility Product Constant
Equilibrium constant that applies to the dissolution of a slightly soluble compound.
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
Description of the quantitative relationships among substances as they participate in chemical reactions.
