In chemiluminescence, for example, some chemical reaction occurs that gives off energy. That energy is then used to excite electrons and produce luminescence. Many students are familiar with devices called cyalume sticks. When one of these sticks is broken, two chemicals are released and begin to ...
Basically, any compound contains chemical energy that can be released when its chemical bonds are broken. Any substance that can be used as a fuel contains chemical energy. Examples of matter containing chemical energy include: Coal: Combustion reaction converts chemical energy into light and heat....
Bioluminescence, emission of light by an organism or by a laboratory biochemical system derived from an organism. It results from a chemical reaction (chemiluminescence) that converts chemical energy to radiant energy, and it occurs sporadically in a wid
Chemical energyresults fromchemical reactionsbetween atoms or molecules. There are differenttypes of chemical energy, such as electrochemical energy and chemiluminescence.

Levels of organosulfur compounds in crudepetroleumas low as 10 parts per billion or less may have adetrimentaleffect on metallic catalysis or may cause unpleasant odours. These very low sulfur levels are detected usinggas chromatographswith sulfurchemiluminescenceor ...
