Compounds that contain only carbon 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...
- 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?
- 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...
- 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...
- 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 Procedure in which one solution is added to another solution until the chemical reaction between the two solutes is complete, the concentration of one solution is known and that of the other is unknown.
Covalent bond resulting from the sharing of four electrons (two pairs) between two atoms.
An impure form of carbon obtained by destructive distillation of coal or petroleum.
The mass action expression under any set of conditions (not necessarily equlibrium), its magnitude relative to K determines the direction in which the reaction must occur to establish equilibrium.
A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
Ytterbia is a colorless compound, Yb2O3, used in certain alloys and ceramics. Also known as ytterbium oxide.
Lead Storage Battery
Secondary voltaic cell used in most automobiles.
The transfer of an electron from one energy level to another.
Net Ionic Equation
Equation that results from canceling spectator ions and eliminating brackets from a total ionic equation.
Trapping of heat at the surface of the earth by carbon dioxide and water vapour in the atmosphere.
Decomposition by heating a substance in the presence of a catalyst and in the absence of air.
Benzene and its derivatives.
A form of energy that flows between two samples of matter because of their differences in temperature.
Electrolytic cell for the commercial electrolysis of molten sodium chloride. For further information see Electrochemistry or Fuel Cells.
Equilibrium or Chemical Equilibrium
A state of dynamic balance in which the rates of forward and reverse reactions are equal, the state of a system when neither forward or reverse reaction is thermodynamically favored.
Isomers that differ only in the way that atoms are oriented in space, consist of geometrical and optical isomers.
Method by which hydrophobic (water-repelling) particles of an ore are separated from hydrophilic (water-attracting) particles of a metallurgical pretreatment process.
A state of dynamic balance in which the rates of forward and reverse reactions are equal, there is no net change in concentrations of reactants or products while a system is at equilibrium.
The temperature at which the vapor pressure of a liquid is equal to the applied pressure, also the condensation point
