<em>Diamond and graphite are allotropes of carbon and have various differences in their physical properties.</em>
Explanation:
<u>Diamond:</u>
- It is crystalline in nature
- Each Each C is
hybridized and forms 4 covalent binds with neighboring C atoms - The geometry is tetrahedral
- C-C bond length is 154 pm
- It has rigid covalent boning which is difficult to break.
- It acts as an electric insulator
<u>Graphite:</u>
-
It has layered structure
- Each C atom is sp2 hybridized and forms 3 sigma bonds with 3 other C atoms. Fourth electron forms pi bond.
-
The geometry is planar
- C-C bond length is 141.5 pm
- It is soft. Its layers can be separated easily
- It is good conductor of electricity.
This is the comparison of the physical properties of two forms of carbon: diamond and graphite
Answer: The concentration of hydrogen ion is 2.5 x 10∧-3.
Explanation:
It is well known that; pH + pOH = 14
∴ pH + 11.40 = 14
pH = 14 -11.40 = 2.60
Remember that,
pH = - Log [ H+ ]
2.60 = - log [H+]
To get the hydrogen ion concentration, we take the anti-log of 2.60.
[H+] = Antilog 2.60 = 2.5 x 10∧-3.

Answer:scientists finished deciding the human genome in 2001. This research helped genetics analyze and islote sections of DNA for investigation. Without this information and the technology invented during the Human Genome Project, Hugh would not have been able to extract portions of his daughters DNA. Also, he wouldn’t have been able to see the genes that did not function properly in his daughters DNA.
Explanation: this is a right answer for PLATO.
