Iron oxide formula
12 December 2007 Chemists in Japan and France have produced a new iron oxide with a sheet-like structure that could be used in fuel cells and sensors. The team produced the compound by gentle reduction in a way that may also yield other unusual and potentially useful crystalline structures. Hiroshi Kageyama from the University of Kyoto and colleagues started with a conventional…

Aluminium oxide Hazards
Although aluminum oxide is certainly abrasive, it is also a skin irritant with a very questionably safety record. In any case, it is unquestionably unpleasant. If it gets into your eyes, it can scratch your cornea. If it gets into your ears, it can cause earaches. If it gets into your mouth, you will experience the unpleasant sensation of tooth enamel grinding away until it’s…

Are nitric oxide supplements safe
What Is It? Nitric Oxide is a gas inside your body that helps the cells in your system communicate with each other. It is a compound that consists of one oxygen atom and one nitrogen atom. This gas is produced when Arginine, an amino acid, is broken down by enzymes. Scientists claim this gas has almost unlimited functions in the body, controlling blood circulation and regulating…

Periodic table oxidation number
Questions, Page 123: 1) Does either bar graph reveal a repeating, or cyclic, pattern? Describe any patterns you observe. By looking at both bar graphs side by side, we noticed that the number of atoms added to the element directly correlated to the boiling points (in °K). The more atoms added, the higher the boiling point. 2) Are these graphs consistent with patterns found…

Oxidation Numbers Chart
Top The oxidation number (or oxidation state) of an element represents the number of electrons that are gained, transferred or shared. The oxidation number of an element is a positive or negative number assigned to an element which can be used to predict the chemical bonds that it will form with other elements. An atom has a positive oxidation number when it loses electrons…

Uranium Oxides
Uranium can take many chemical forms. In nature, uranium is generally found as an oxide, such as in the olive-green-colored mineral pitchblende. Uranium oxide is also the chemical form most often used for nuclear fuel. Uranium-fluorine compounds are also common in uranium processing, with uranium hexafluoride (UF6) and uranium tetrafluoride (UF4) being the two most common…

Definition of oxidize
To oxidize is to chemically combine with oxygen. If you have a rusty car, that is the result of oxidizing. In chemistry class, you ll probably learn about oxidizing, which is when oxygen molecules combine with other molecules to produce an oxide. The most common example of oxidizing is rusting: oxygen interacts with iron molecules to produce the new (and unwelcome) iron oxide…
