Voltaic cells in which the reactants (usually gases) are supplied continuously.
A voltaic cell that converts the chemical energy of a fuel and an oxidizing agent directly into electriacl energy on a continuous basis.
- 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...
- 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...
- 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...
A measure of the intensity of heat, i.e. the hotness or coldness of a sample. or object.
A substance that conducts electricity well in a dilute aqueous solution.
Energy that matter possesses by virtue of its position, condition or composition.
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.
One of the two mirror-image forms of an optically active molecule.
A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
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."
A system in which controlled nuclear fisson reactions generate heat energy on a large scale, which is subsequently converted into electrical energy.
Covalent bond in which there is an unsymmetrical distribution of electron density.
A listing of metals (and hydrogen) in order of decreasing activity.
Solubility Product Constant
Equilibrium constant that applies to the dissolution of a slightly soluble compound.
Heat of Fusion
The amount of heat required to melt one gram of solid at its melting point with no change in temperature. Usually expressed in J/g. The molar heat of fusion is the amount of heat required to melt one mole of a solid at its melting point with no change in temperature and is usually expressed in kJ/mol.
Water containing Fe3+, Ca2+, and Mg2+ ions, which forms precipates with soap.
Any kind of matter all specimens of which have the same chemical composition and physical properties.
The spontaneous disintegration of atomic nuclei.
A salt containing an ionizable OH group.
Amount of solute per unit volume or mass of solvent or of solution.
An area that may be used for work with carcinogens, reproductive toxins, or substances that have a high degree of acute toxicity. A designated area may be the entire laboratory, an area of a laboratory, or a device such as a laboratory hood.
Pair of electrons residing on one atom and not shared by other atoms, unshared pair.
Aufbau ('building up') Principle
Describes the order in which electrons fill orbitals in atoms.
