A substance whose aqueous solutions do not conduct electricity.
- 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?
An atomic emission or absorption spectrum.
Ability to conduct electricity.
A physical state of matter which exists at extremely high temperatures in which all molecules are dissociated and most atoms are ionized.
Refers to different atomic forms of all elements in contrast to ?isotopes?, which refer only to different atomic forms of a single element.
The smallest repeating unit of a substance. The molecule for nonionic substances
Compound in which an oxygen atom is bonded to two alkyl or two aryl groups, or one alkyl and one aryl group.
A series of compounds in which each member differs from the next by a specific number and kind of atoms.
The degree of polymerization, the average number of monomer units per polymer unit.
Either the oxidation part or the reduction part of a redox reaction.
Hess' Law of Heat Summation
The enthalpy change for a reaction is the same whether it occurs in one step or a series of steps.
Heat of Condensation
The amount of heat that must be removed from one gram of a vapor at it's condensation point to condense the vapour with no change in temperature.
Isomers that result from the interchange of ions inside and outside the coordination sphere.
A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.
The chemistry of substances that contain carbon-hydrogen bonds.
Faraday's Law of Electrolysis
One equivalent weight of a substance is produced at each electrode during the passage of 96,487 coulombs of charge through an electrolytic cell.
Ability of a substance to exhibit amphiprotism by accepting donated protons.
The elements in a horizontal row of the periodic table.
Physical properties of solutions that depend upon the number but not the kind of solute particles present.
A Lewis base in a coordination compound.
Absolute Entropy (of a substance)
The increase in the entropy of a substance as it goes from a perfectly ordered crystalline form at 0 °K (where its entropy is zero) to the temperature in question.
Entropy is a measure of the “dilution” of thermal energy.
