Carbon exists in three alloptropic forms because of the difference of arangement of atoms, bond angles and geometry.In DIAMOND each carbon atom is surrounded by four other carbon atoms having a tetrahedral geometry; GRAPHITE has trigonal geomety arrangged in layers where one layer can be slipped from the layer below it; BUCKY BALL have carbon atoms arranged in foot-ball pattern.
Two possible reactions:In excess of oxygen (in air)C + O2 --> CO2In less oxygen rich atmosphere (incomplete combustion, toxic fumes):2C + O2 --> 2CO
Lens exists in two forms, diverging, or converging. They affect light rays equally, but in contrasting manners.
No because gold is not alive.answer 2. To be organic, a compound needs to contain carbohydrates, or at least carbon forms. Gold, beautiful as it is, does not.
Is this a trick question? Carbon forms four covalent bonds Carbon is sometimes ionic - e.g. in the alkali metal carbides Carbon can bond to itself- Carbon forms long chains- the best of all the elements Carbon is found in all organic molecules by definition. the least well known characteristic is ionic where it forms the ions C4-, C22-, C34-
Lithium is the lightest metal. Its density is 0.53 gram/cm3 .Carbon exists in at least 4 different 'allotropes',with the following densities:Amorphous carbon (charcoal, soot, etc.) . . 1.8 to 2.1Buckminsterfullerene C60 . . . . . . . .. . . . . . 1.69Graphite (pencil lead, dry lubricant, etc.) . . 1.9 to 2.3Diamond. . . . . . . . . . . . . . . . . . . . . . . . . . . 3.50 to 3.53So if you have equal volumes of lithium and carbon, the carbon hasat least 3.19 times the mass of the lithium, and possibly as much as6.66 times its mass.
In the context of alkenes, unsaturated means that the molecule contains at least one carbon-carbon double bond. This double bond creates a region of unsaturation where the molecule can potentially undergo addition reactions to increase its saturation level by breaking the double bond and adding new atoms or groups.
Graphite, diamonds, Lonsdaleite, C60 (Buckminsterfullerene), C540 Fullerene, C70 Fullerene, Amorphous carbon, and Single-walled carbon nanotube are all solid allotropes of carbon. Allotropes are different structural forms of the same element.
Helium, Oxygen, Carbon Dioxide (least to most dense)
The correct order of forms of coal from the first stage of development to the last stage of development is peat, lignite, bituminous, anthracite. Peat is the first stage and is the least carbon-rich, while anthracite is the last stage and is the most carbon-rich form of coal.
An alkene
carbon is in a LOT of things, in the very least, carbon can be found in all organic matter.
