In chemistry absorption can mean two things: Firstly it can imply that powerful forces exist holding two substances together, and that seperation of the two is not easily accomplished. Secondly it can [..]

This is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemica [..]

A chemical or mechanical process which takes place without heat entering or leaving the system. The term is only applicable to enclosed and isolated systems - so in essence is idealistic and purely th [..]

If any compound, solid, liquid or gas, is loosely held by weak attraction to the surface of a solid it is said to have undergone adsorption. This process is much weaker and less permanent than absorpt [..]

Several of the great Greek philosophers considered all matter to be composed of four basic "elements", fire, air, earth and water, and that all materials were had these components mixed in d [..]

An organic compound containing the -CHO group (see below). An example of these distinct aromatic compounds is formaldehyde.

A water soluble hydroxide on one of the alkali metals. The term is virually synonymous with the term base. An example is Sodium Hydroxide, NaOH.

Group II of the periodic table consists of the alkaline earth metals. They are bivalent and react with water to produce water soluble hydroxides.

This is the correct chemical term for compounds known as paraffins. They are considered the simplest organic compounds and are a family of chain hydrocarbons having the general formula C2H2n+2. All of [..]

These compounds are also similar to alkanes. They have the general formula C2H2n-2 corresponding to carbon chains with a triple carbon-carbon bond included. The simplest member of this family is ethyn [..]
