Answer:
Explanation:
Carbon-14 has a mass number of 14, and Carbon-12 has a mass number of 12. Every carbon atom must have six protons, so Carbon-14 has eight neutrons and Carbon-12 has six neutrons. Elements with the same atomic number but different atomic masses are isotopes.
Answer:
e) halogens
Explanation:
Halogens -
It is the group of elements present in the group 17 of the periodic table .
Oxidizing agent -
It is the process by which the process of oxidation takes place ,
It is the tendency of an element to oxidize other element by accepting electrons and reducing itself .
In the electrochemical series ,
Halogens are placed on the top of the series , and hence have the capability to act as a very good oxidizing agent , as they can easily accept electrons other elements and reduce themselves and thereby by oxidizing the other element .
The correct answer of the given question above would be FINGERPRINTS. Molds might be used for evidence such as fingerprints. This is now a possibility of replicating fingerprints which is called a fingerprint mold. Hope this is the answer you are looking for.
Answer:
ΔG = 18KJ/mol
Explanation:
Given data:
ΔS = 0.09 Kj/mol.K
ΔH = 27 KJ/mol
Temperature = 100 K
ΔG = ?
Solution:
Formula:
ΔG = ΔH - TΔS
ΔS = entropy
ΔH = enthalpy
by putting values,
ΔG = 27 KJ/mol - 100K(0.09 Kj/mol.K)
ΔG = 27 KJ/mol - 9 KJ/mol
ΔG = 18KJ/mol
The entire sun is powered by fusion, which is a form of nuclear energy. Infrared, visible, and ultraviolet lights that are released by the sun are all forms of electromagnetic energy that the sun releases. Finally, the sun is a giant burning ball of gas, and that is the heat energy of the sun :D
Hope this helped! :D
