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.
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
Refers to an optically active substance that rotates the plane of plane polarized light clockwise, also called dextro.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
Unit of electrical charge.
Electron Deficient Compounds
Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.
Industrial process by which sulfur trioxide and sulfuric acid are produced from sulfur dioxide.
Numbers that describe the energies of electrons in atoms, derived from quantum mechanical treatment.
Beginning in the third energy level, aset of five degenerate orbitals per energy level, higher in energy than s and p orbitals of the same energy level.
Ytterbia is a colorless compound, Yb2O3, used in certain alloys and ceramics. Also known as ytterbium oxide.
The rotation of plane polarized light by one of a pair of optical isomers.
A very slightly soluble compound.
The prefix used to indicate that groups are located on the same side of a bon about which rotation is restricted.
Lead Storage Battery
Secondary voltaic cell used in most automobiles.
Mass Action Expression
For a reversible reaction, aA + bB cC + dD the product of the concentrations of the products (species on the right), each raised to the power that corresponds to its coefficient in the balanced chemical equation, divided by the product of the concentrations of reactants (species on the left), each raised to the power that corresponds to its coefficient in the balanced chemical equation. At equilibrium the mass action expression is equal to K, at other times it is Q.[C]c[D]d [A]a[B]b = Q, or at equilibrium K.
A helium nucleus.
A series of very closely spaced, nearly continuous molecular orbitals that belong to the crystal as a whole.
A sample of matter composed of two or more substances, each of which retains its identity and properties.
Molecular Orbital Theory
A theory of chemical bonding based upon the postulated existence of molecular orbitals.
Transition State Theory
Theory of reaction rates that states that reactants pass through high-energy transition states before forming products.
A group of atoms derived from an alkane by the removal of one hydrogen atom.
The amount of heat required to raise the temperature of one gram of water from 14.5°C to 15.5°C. 1 calorie = 4.184 joules.
