A fairly strong dipole-dipole interaction (but still considerably weaker than the covalent or ionic bonds) between molecules containing hydrogen directly bonded to a small, highly electronegative atom, such as N, O, or F.
- 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...
A colorless, nonvolatile solid, XeO3, explosive when dry: in solution it is called xenic acid.
A technique for separation of ions by rate and direction of migration in an electric field.
Isomers that result from the interchange of ions inside and outside the coordination sphere.
An ionization reaction between identical molecules.
Integral number of protons in the nucleus, defines the identity of element.
The ratio of the density of a substance to the density of water.
A measure of the amount of matter in an object. Mass is usually measured in grams or kilograms.
Spectrum that contains all wave-lengths in a specified region of the electromagnetic spectrum.
Substances that flow freely, gases and liquids.
The amount of energy absorbed in the process in which an electron is added to a neutral isolated gaseous atom to form a gaseous ion with a 1- charge, has a negative value if energy is released.
Heat of Condensation
The amount of heat that must be removed from one gram of a vapor at it's condensation point to condense the vapour with no change in temperature.
Alpha (a) Particle
Helium ion with 2+ charge, an assembly of two protons and two neutrons.
Colloidal suspension of a liquid in a liquid.
A device for measuring pressure.
Industrial process by which sulfur trioxide and sulfuric acid are produced from sulfur dioxide.
Band Theory of Metals
Theory that accounts for the bonding and properties of metallic solids.
Electrochemical cells in which electrical energy causes nospontaneous redox reactions to occur. An electrochemical cell in which chemical reactions are forced to occur by the application of an outside source of electrical energy.
Regular periodic variations of properties of elements with atomic number (and position in the periodic table).
A natural deposit containing a mineral of an element to be extracted.
Two methyl groups of the same carbon atom.
