Binary compounds of boron and hydrogen.
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
Reactions that do not go to completion and occur in both the forward and reverse direction.
The minimum amount of energy required to remove the most loosely held electron of an isolated gaseous atom or ion.
The oxide of a metal that reacts with water to form a base.
Nickel-cadmium cell (Nicad battery)
A dry cell in which the anode is Cd, the cathode is NiO2, and the electrolyte is basic.
Reactions in which one element displaces another from a compound.
Covalent bond resulting from the sharing of two electrons (one pair) between two atoms.
Specific distribution of electrons in atomic orbitals of atoms or ions.
A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
Protection of a metal (making ir a cathode) against corrosion by attaching it to a sacrifical anode of a more easily oxidized metal.
The minimum mass of a particular fissionable nuclide in a given volume required to sustain a nuclear chain reaction.
Compound in which an oxygen atom is bonded to two alkyl or two aryl groups, or one alkyl and one aryl group.
Any of a number of lines corresponding to definite wavelengths of an atomic emission or absorption spectrum, represents the energy difference between two energy levels.
A colorless, crystalline compound, XeF6, that melts at 50°C to a yellow liquid, and boils at 75°C.

Valence bond designation for a complex in which the metal ion utilizes d orbitals in the outermost (occupied) shell in hybridization.
The heat content of a specific amount of substance, defined as E= PV.
Description of a chemical reaction by placing the formulas of the reactants on the left and the formulas of products on the right of an arrow.
A rare metallic element found in gadolinite and forming compounds resembling those of yttrium. Symbol: Yb, at. wt.: 173.04, at. no.: 70, sp. gr.: 6.96. Cf."rare-earth element."
A salt containing an ionizable hydrogen atom. Acidic salt does not necessarily produce acidic solutions.
A number that indicates how smoothly a gasoline burns.
A form of energy that flows between two samples of matter because of their differences in temperature.
