Graphite and diamond are both made from carbon atoms.

A) List some of the physical characteristics of each.

B) Give one application for graphite and one for diamond.

C) If both materials are made of carbon, why does such a difference in properties exist?

Expert Solution

Both graphite and diamond are the allotropes of carbon

(A)

PHYSICAL CHARACTERISTICS OF GRAPHITE

1. Graphite is the good conductor of Electricity due to free electron

2.Graphite exist in the form of hexagonal

3. Graphite is opaque

4. Graphite is very soft and behave as a lubricant

PHYSICAL CHARACTERISTICS OF DIAMOND

1. Diamond is a insulator

2.Diamond has isometric structure and covalent bond

3. Diamond usually very transparent

4. It is the hardest mineral in this world.

5. Diamond has perfect cleavage

(B)

APPLICATION OF GRAPHITE

1. It is used in nuclear reactor to control the speed of the nuclear fission reaction

APPLICATION OF DIAMOND

1. It is used for cutting, grinding , drilling and polishing in industries

(C) Although both are the allotropes of carbon but they have different properties due to their structure.In Diamond the carbon atom are arranged tetrahedrally and where as the Graphite has layered structure. Each carbon of graphite is bonded with another three carbon atom and arranged at the corner in the form of hexagons. In graphite, one mobile electron is present between the layer of Carbon and which mainly helps for the conduction of electricity. But in Diamond there is no free electron to conduct electricity.

Black Diamond, Inc., a manufacturer of carbon and graphite products for the aerospace and transportation industries, is considering several funding alternatives for an investment project. To finance the project, the company can sell 1,000 20-year bonds with a $1,000 face value, 6% coupon rate. The bonds require an average discount of $50 per bond and flotation costs of 3% of bond price. The company can also sell 5,000 shares of preferred stock that will pay a $2.5 dividend per share...

Graphite fiber is made by modifying the microstructure into long, thin ribbons, in which the carbon sheets parallel the plane of the ribbon. The ribbons are then rolled, somewhat as one would roll a newspaper, to form the graphite fiber. While normal graphite is weak, graphite fiber is extremely strong when pulled along the fiber axis. Explain in terms of the microstructure and the bonding in graphite.

Avagadro's number of carbon atoms have a mass of 12.0 g. Two identical graphite spheres each have a mass of m = 4.21 g. If we could transfer one electron from each atom in the first sphere to an atom in the second sphere, what would be the magnitude of the attractive force between the spheres if they are separated by 1.00 m?

5. A scientist proposes using radioactive tracers to demonstrate that the carbon atoms from carbon dioxide end up incorporated into glucose molecules as the result of photosynthesis. In order to test this hypothesis, the scientist conducts the following experiment: A group of plants are illuminated with light of a wavelength that is optimal for photosynthesis. The light is turned off, and the plants are kept in darkness for all remaining steps in the investigation. Radiolabeled CO2 is introduced to the...

An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 163 g (HINT: Assume all the carbon is 12C and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 21 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was 1.3×10-12 & the half-life of 14C is 5730 y. age of...
