A quantity that characterizes the position of equilibrium for a reversible reaction, its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
- 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 compound containing oxygen in the -1 oxidation state. Metal peroxides contain the peroxide ion, O22
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
Consisting of different elements.
A sample of matter composed of two or more substances, each of which retains its identity and properties.
The direct solidification of a vapor by cooling, the reverse of sublimation.
A white, needlelike, crystalline, water-soluble solid or syrup, C6H10O8, usually made by the oxidation of cane sugar, glucose, or starch by nitric acid. Also called "Glucaric acid."
Trapping of heat at the surface of the earth by carbon dioxide and water vapour in the atmosphere.
Electron emitted from the nucleus when a neuton decays to a proton and an electron.
The number of moles of a component of a mixture divided by the total number of moles in the mixture.
A neutron ejected at high kinetic energy in a nuclear reaction.
Different forms of the same element in the same physical state.
In aqueous solution, the process in which a molecular compound reacts with water and forms ions.
Reaction in which two substances (elements or compounds) combine to form one compound.
A gas filled tube which discharges electriaclly when ionizing radiation passes through it.
Also called "phenosafranine". A purplish-red, water-soluble dye, C18H14N4, used for textiles and as a stain in microscopy.
Law of Conservation of Matter
There is no detectable change in the quantity of matter during an ordinary chemical reaction.
The unit used to express dipole moments.
The reaction of an acid with a base to form a salt and water. Usually, the reaction of hydrogen ions with hydrogen ions to form water molecules.
The pentosan occurring in woody tissue that hydrolyzes to xylose: used as a source of furfural.
The solid and liquid states.
