Classification By Carbon Content
Nomenclature And Classifiion Common Names ...
Carbohydrates can be named based on the length of the carbon chain, the functional groups present on the sugar, and the stereochemistry of the sugar.. To be classified as a carbohydrate, a molecule must have at least a 3carbon backbone, an aldehyde or ketone group, and at least two hydroxyl groups.. Simple carbohydrates such as glucose, lactose, or dextrose, end with an "ose".

coal classifiion | Types Facts | Britannica
Coal classifiion, any of various ways in which coal is grouped. Most classifiions are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifiions are important because they provide valuable information to commercial users (, for power generation and coke manufacturing) and to researchers studying the origin of coal.

Paraffins: These can make up 15 to 60% of crude and have a carbon to hydrogen ratio of 1:2, which means they contain twice the amount of hydrogen as they do carbon. These are generally straight or branched chains, but never cyclic (circular) compounds. Paraffins are the desired content in crude and what are used to make fuels.

The Carbon Cycle
The Slow Carbon Cycle. Through a series of chemical reactions and tectonic activity, carbon takes between 100200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year.

GuanineplusCytosine Content. The G+C content in bacterial DNA ranges from about 25 to 75 percent. This percentage is specific, but not exclusive, for a species; two strains with a similar G+C content may or may not belong to the same species. If the G+C contents are very different, however, the strains cannot be members of the same species.
