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...

Ozone
We breathe 24 hours a day, 7 days a week, consuming about 25 kg of air every day. It turns out that we practically predetermine our health by the air we breathe.

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...

Limiting Reactant
Substance that stoichiometrically limits the amount of product(s) that can be formed.
Linkage Isomers
Isomers in which a particular ligand bonds to a metal ion through different donor atoms.
Sulfuric Acid
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.
Critical Pressure
The pressure required to liquefy a gas (vapor) at its critical temperature.
Primary Standard
A substance of a known high degree of purity that undergoes one invariable reaction with the other reactant of interest.
Weak Electrolyte
A substance that conducts electricity poorly in a dilute aqueous solution.
xylose
A colorless, crystalline pentose sugar, C5H10O5, derived from xylan, straw, corncobs, etc., by treating with heated dilute sulfuric acid, and dehydrating to furfural if stronger acid is used.
Solubility Product Principle
The solubility product constant expression for a slightly soluble compound is the product of the concentrations of the constituent ions, each raised to the power that corresponds to the number of ions in one formula unit.
Metallic Bonding
Bonding within metals due to the electrical attraction of positively charges metal ions for mobile electrons that belong to the crystal as a whole.
Amine Complexes
Complex species that contain ammonia molecules bonded to metal ions.
