A compound that contains more than one double bond per molecule.
- 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...
- 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...
- 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?
- 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...
- 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...
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.
The capacity to do work or transfer heat.
Unsaturated hydrocarbons that contain one or more carbon-carbon double bonds.
Ability of a substance to exhibit amphiprotism by accepting donated protons.
Fine divided solid particles suspended in polluted air.
A listing of metals (and hydrogen) in order of decreasing activity.
A substance that speeds up a chemical reaction without being consumed itself in the reaction.
A substance that alters (usually increases) the rate at which a reaction occurs.
A catalyst that exists in the same phase (solid, liquid or gas) as the reactants. The process is called Homogeneous Catalysis.
A packet of light or electromagnetic radiation, also called quantum of light.
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."
The arrangement of atoms (not lone pairs of electrons) around a central atom of a molecule or polyatomic ion.
Reactions that do not go to completion and occur in both the forward and reverse direction.
Crystal Field Stabilization Energy
A measure of the net energy of stabilization gained by a metal ion's nonbonding d electrons as a result of complex formation.
Equilibria involving only one species in a single phase. For example, all gases, all liquids or all solids.
Energy that matter possesses by virtue of its position, condition or composition.
At the same temperature and pressure, equal volumes of all gases contain the same number of molecules.
The complex series of reactions by which nitrogen is slowly but continually recycled in the atmosphere, lithosphere and hydrosphere.
A device used to measure the heat transfer between system and surroundings.
The mass percent of each element in a compound.
The mass of one formula unit of a substance in atomic mass units.
