An ionization reaction between identical molecules.
- 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?
- 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...
- 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...
- 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...
- 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...
Valence Bond Theory
Assumes that covalent bonds are formed when atomic orbitals on different atoms overlap and the electrons are shared.
Short-lived species formed by the collision of dissolved ions of opposite charges.
The properties of the elements are periodic functions of their atomic numbers.
Law of Conservation of Matter and Energy
The total amount of matter and energy available in the universe is fixed.
Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.
Isomers involving exchanges of ligands between complex cation and complex anion of the same compound.
The quantity of product formed by the interaction of two or more substances, generally expressed as a percentage of the quantity obtained to that theoretically obtainable.
Substances consisting largely of hydrocarbons, derived from decay of organic materials under geological conditions of high pressure and temperature (metamorphism) include coal, petroleum, natural gas, peat and oil shale. For further information see Fuel Chemistry
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.
Attractive interactions between polar molecules, that is, between molecules with permanent dipoles.
A large molecule consisting of chains or rings of linked monomer units, usually characterized by high melting and boiling points.
A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
of or derived from saccharin or a saccharine substance.
The number of repeating corresponding points on a wave that pass a given observation point per unit time.
The prefix used to indicate that groups are located on the same side of a bon about which rotation is restricted.
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
CA3COOH, clear, colorless liquid, pungent odor. Boiling point 140C, flash point 54C (closed cup), autoignition temperature 38OC.
A salt or ester of salicylic acid.
The relative amounts of reactants and products involved in a reaction, maybe the ratio of moles. millimoles, or masses.
Reaction in which two substances (elements or compounds) combine to form one compound.
