Substances that flow freely, gases and liquids.
- 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...
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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?
Density is the ratio b/w Mass and Volume: D=M/V
Metal with low ionization energy that loses electrons readily to form cations.
An element below and to the left of the stepwise division (metalloids) in the upper right corner of the periodic table, about 80% of the known elements are metals.
The smallest particle of an element or compound capable of a stable, independent existence.
Compound containing the O-C-N group.Compound that can be considered a derivative of ammonia in which one or more hydrogens are replaced by a alkyl or aryl groups.
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
The rotation of plane polarized light by one of a pair of optical isomers.
Many representative elements attain at least a share of eight electrons in their valence shells when they form molecular or ionic compounds, there are some limitations.
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
Heat of Crystallization
The amount of heat that must be removed from one gram of a liquid at its freezing point to freeze it with no change in temperature.
Molecule formed by combination of two smaller (identical) molecules.
Compounds that contain the same number of the same kinds of atoms in different geometric arrangements.
Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.
The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity. In these processes a small amount of mass is converted to energy according to the relationship E = mc2, where E is energy, m is mass, and c is the speed of light.
Compound in which an alkyl or aryl group and a hydrogen atom are attached to a carbonyl group and a hydrogen atom are attached to a carbonyl group, general formula, O-R-C-H
An equilibrium in which processes occur continuously, with no net change. When two (or more) processes occur at the same rate so that no net change occurs.
At constant pressure the volume occupied by a definite mass of gas is directly proportional to its absolute temperature.
Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
Protection of a metal (making ir a cathode) against corrosion by attaching it to a sacrifical anode of a more easily oxidized metal.
For acid-base titrations, organic compounds that exhibit different colors in solutions of different acidities, used to determine the point at which reaction between two solutes is complete.
