I think iron because the other options are all bad conductors.
A and C are incorrect because they are not complete transfer of valence electrons. Ionic bonds best to form a neutral molecule
Answer:
The change in entropy is -1083.112 joules per kilogram-Kelvin.
Explanation:
If the water is cooled reversibly with no phase changes, then there is no entropy generation during the entire process. By the Second Law of Thermodynamics, we represent the change of entropy (
), in joules per gram-Kelvin, by the following model:
![s_{2} - s_{1} = m\cdot c_{w} \cdot \int\limits^{T_{2}}_{T_{1}} {\frac{dT}{T} }](https://tex.z-dn.net/?f=s_%7B2%7D%20-%20s_%7B1%7D%20%3D%20m%5Ccdot%20c_%7Bw%7D%20%5Ccdot%20%5Cint%5Climits%5E%7BT_%7B2%7D%7D_%7BT_%7B1%7D%7D%20%7B%5Cfrac%7BdT%7D%7BT%7D%20%7D)
(1)
Where:
- Mass, in kilograms.
- Specific heat of water, in joules per kilogram-Kelvin.
,
- Initial and final temperatures of water, in Kelvin.
If we know that
,
,
and
, then the change in entropy for the entire process is:
![s_{2} - s_{1} = (1\,kg) \cdot \left(4190\,\frac{J}{kg\cdot K} \right)\cdot \ln \frac{288.15\,K}{373.15\,K}](https://tex.z-dn.net/?f=s_%7B2%7D%20-%20s_%7B1%7D%20%3D%20%281%5C%2Ckg%29%20%5Ccdot%20%5Cleft%284190%5C%2C%5Cfrac%7BJ%7D%7Bkg%5Ccdot%20K%7D%20%5Cright%29%5Ccdot%20%5Cln%20%5Cfrac%7B288.15%5C%2CK%7D%7B373.15%5C%2CK%7D)
![s_{2} - s_{1} = -1083.112\,\frac{J}{kg\cdot K}](https://tex.z-dn.net/?f=s_%7B2%7D%20-%20s_%7B1%7D%20%3D%20-1083.112%5C%2C%5Cfrac%7BJ%7D%7Bkg%5Ccdot%20K%7D)
The change in entropy is -1083.112 joules per kilogram-Kelvin.
Answer:
Graphite is insoluble in water and organic solvents - for the same reason that diamond is insoluble. Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds in graphite. conducts electricity.

Answer:
Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
