A solid compound that contains a definite percentage of bound water.
- 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'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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
Mixing of metal with other substances (usually other metals) to modify its properties.
Any state other than the ground state of an atom or molecule.
Number of moles of solute per litre of solution.
Molecular orbital resulting from head-on overlap of two atomic orbitals.
The relative amounts of reactants and products involved in a reaction, maybe the ratio of moles. millimoles, or masses.
Equation for a chemical reaction in which all formulas are written as if all substances existed as molecules, only complete formulas are used.
The sum of the molalities of all solute particles in a solution.
A substance that conducts electricity poorly in a dilute aqueous solution.
Rods of materials such as cadmium or boron steel that act as neutron obsorbers (not merely moderaters) used in nuclear reactors to control neutron fluxes and therfore rates of fission.
Y2O3: A white, water-insoluble powder, Y2O3, used chiefly in incandescent gas and acetylene mantles.
Freezing Point Depression
The decrease in the freezing point of a solvent caused by the presence of a solute.ing Point
The concept in which two or more equivalent dot formulas for the same arrangement of atoms (resonance structures) are necessary to describe the bonding in a molecule or ion.
Fine divided solid particles suspended in polluted air.
Colloidal particles that repel water molecules.

Decomposition by heating a substance in the presence of a catalyst and in the absence of air.
Reactions in which one element displaces another from a compound.
Energy that is propagated by means of electric and magnetic fields that oscillate in directions perpendicular to the direction of travel of the energy.
