Flames are hot, lively, and colorful. Sadly, if you’re always burning the same fuel, that color gets rather monotonous. You expect that wood, wax, and paper will produce orange flames. Natural gas and alcohol will burn blue. There’s not a lot of variety...
How is helium distilled?
By: Nigel Holmes
Despite being abundant throughout the universe, helium is actually rather uncommon here on earth. Trace amounts exist in the atmosphere and it can be extracted through liquefaction (cooling air to extremely low temperatures,) but this approach is too expensive for commercial use. The more...

The valence bond theory is a quantum mechanics theory that, like the molecular orbitals theory, tries to explain the chemical bonding between atoms. Each of these theories have different perspectives on how the bond forms. The valence bond theory is a theory which assumes that...

Molecular orbital theory is a theoretical method in chemistry that tries to give an explanation to the chemical bond in terms of molecular orbitals formation that are formed by the addition and subtraction of two atomic orbital functions. This method tries to rationalize the formation...
How to make a salt map mixture for 3D maps
By: Darlene Michaud
Salt map mixture is used to make hills and valleys on a topographical map or 3D map. It's an excellent mixture to use for school science projects. You can also use this salt map mixture for making box dioramas. Below are two salt map mixture...
Interesting facts about gold
By: Dale Creelman
Searched for, killed for, hoarded, worshiped, used as money , used to decorate man and building, this shiny yellow metal has fascinated mankind since long before the ancient Egyptians first began mining it. From gold objects made by Cro-Magnon man to today's miniature gold pathways...

The angular momentum is a physical variable that is characteristic of rotating systems. In classical mechanics, angular momentum is associated with macroscopic objects that are rotating, such as the movement of the planets of the solar system around the sun. This rotational movement leads to...
Chemistry experiments for middle schoolers
By: Adam Abdelrahim
One of the most hated courses both in middle and high school is chemistry. Many fear this topic because of its assumed difficulty. One method to raising the interest in this field is through demonstrations of fun little labs. Below I will provide a few...

In this article, the subject of unsaturated organic compounds is discussed. Usually organic compounds are by definition compounds which involve chemical bonding between carbon and hydrogen atoms. Unsaturation of hydrocarbons refers to the presence of double bonds between two adjacent carbon atoms. Organic chemicals are...
Christmas 2010: Chemistry gift ideas for children
By: Angela La Fon
Are you looking for some hot chemistry gifts for Christmas 2010? Some kids are naturally drawn to chemistry and others are terrified of the word alone. If we present chemistry as what it is, a combining of substances and matter and their reactions, and even...
