Equation that results from canceling spectator ions and eliminating brackets from a total ionic equation.
- 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...
- 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...
- 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...
- 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?
A decrease in the radii of the elements following the lanthanides compared to what would be expected if there were no f-transition metals.
Consisting of only one element.
Forces between individual particles (atoms, molecules, ions) of a substance.
The breaking up of a compound into separate ions.
Any kind of matter all specimens of which have the same chemical composition and physical properties.
A soap-like emulsifer that contains a sulfate, SO3 or a phosphate group instead of a carboxylate group.
Equilibrium constant for the ionization of a weak electrolyte.
Equation relating the rate of a reaction to the concentrations of the reactants and the specific rate of the constant.
Method of dating ancient objects by determining the ratio of amounts of mother and daughter nuclides present in an object and relating the ratio to the object?s age via half-life calculations.
The absolute entropy of a substance in its standard state at 298 K.
Theory of reaction rates that states that effective collisions between reactant molecules must occur in order for the reaction to occur.
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
The material in a distillation apparatus that is to be distilled.
Ability to conduct electricity.
Placing a thin layer of zinc on a ferrous material to protect the underlying surface from corrosion.
Hess' Law of Heat Summation
The enthalpy change for a reaction is the same whether it occurs in one step or a series of steps.
Binary compounds of boron and hydrogen.
Colloidal suspension of a solid dispersed in a liquid, a semirigid solid.
Having the same electronic configurations.
