Which of the following properties of carbon give it particular importance to life? Physical Properties: Carbon is a soft, dull gray or black non-metal that you can scratch with a fingernail. Th density of carbon as graphite is 2.267 g/mL, which means it will sink in water. Chemical Properties: Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide). When the air or oxygen supply is restricted, incomplete combustion to carbon monoxide, CO, occurs.
Weegy: Organisms are made up mostly of carbon. Plants transform carbon from the atmosphere into biologically useful forms that can be used by animals. Carbon is the basis of large and complex biological molecules such as proteins, DNA, and carbohydrates. [ These compounds also include the other major biological elements: hydrogen, oxygen, nitrogen, phosphorous, and sulfur. Small biological molecules have inherent and emergent properties that allow them to be the basis of larger, biologically important molecules. ] (More)
