Number of moles of a solute that dissolve to produce a litre of saturated solution.
- 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...
- 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?
- 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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
The amount of matter that would be converted into energy if an atom were formed from constituent particles.
Acid that can form only one hydronium ion per molecule, may be strong or weak. Acid that contains one ionizable hydrogen atom per formula unit.
Resistance offered by the molecules of a liquid to flow is termed as viscosity.
A sample of matter composed of two or more substances, each of which retains its identity and properties.
A rare trivalent metallic element, found in gadolinite and other minerals. Symbol: Y, at. wt.: 88.905, at. no.: 39, sp. gr.: 4.47. Cf."rare-earth element."
Yttrium has a silver-metallic luster and is relatively stable in air unless finely divided. Turnings of the metal, however, ignite in air if their temperature exceeds 400oC. Yttrium oxide is one of the most important compounds of yttrium and accounts for the largest use. It is widely used in making YVO4 europium, and Y2O3 europium phosphors to give the red color in color television tubes.
High energy particles or rays emitted during the nuclear decay processes.
A term used to describe molecules and polyatomic ions that have one atom in center and four atoms at the corners of a tetrahedron.
Integrated Rate Equation
An equation giving the concentration of a reactant remaining after a specified time, has different mathematical form for different orders of reactants.
A chemical or compound that causes a sudden, almost instantaneous release or pressure, gas, heat and light when subjected to sudden shock, pressure, high temperature or applied potential.
H3P04, Colorless liquid or rhombic crystals, decomposes before it will boil. Used mostly in the metal etchant. Used in cleaning operations to remove encrusted surface matter and mineral scale found on metal equipment such as boilers and steam producing equipment. Also used to brighten metals and remove rust.
The product of the distance separating opposite charges of equal magnitude of the charge, a measure of the polarity of a bond or molecule, a measured dipole moment refers to the dipole moment of an entire molecule.
of or derived from saccharin or a saccharine substance.
Attractive interactions between polar molecules, that is, between molecules with permanent dipoles.
The temperature above which a gas cannot be liquefied, the temperature above which a substance cannot exhibit distinct gas and liquid phases.
The absorption of heat by a system as the process occurs.
Describes processes that absorb heat energy.
A gas formed by boiling or evaporating a liquid.
An organic compound containing a sugar or sugars.
Having the same electronic configurations.
