Characteristic of the post-transition minerals, tendency of the outermost s electrons to remain nonionized or un shared in compounds.
Why do copper products change color, and what is the name of the process?
Probably, every person wants to know, why over time the copper turns green and becomes bloomed. This is easy to explain: that film is called patina.
Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
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...
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...
Use of diamonds
Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...
The number (6.022x10^23) of atoms, molecules or particles found in exactly 1 mole of substance.
Ideal Gas Law
The product of pressure and the volume of an ideal gas is directly proportional to the number of moles of the gas and the absolute temperature.
Two peaks or bands of about equal intensity appearing close together on a spectrogram.
A tube having a very small inside diameter.
The scattering of light by colloidal particles.
A quantity that characterizes the position of equilibrium for a reversible reaction, its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.
Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.
Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.
Unit of electrical charge.
At constant pressure the volume occupied by a definite mass of gas is directly proportional to its absolute temperature.
