Answer:
![\Delta _fS=0.2724\frac{J}{K}](https://tex.z-dn.net/?f=%5CDelta%20_fS%3D0.2724%5Cfrac%7BJ%7D%7BK%7D)
Explanation:
Hello,
In this case, we define the entropy change for such freezing process as:
![\Delta _fS=\frac{n_{Hg}\Delta _fH}{T_f}](https://tex.z-dn.net/?f=%5CDelta%20_fS%3D%5Cfrac%7Bn_%7BHg%7D%5CDelta%20_fH%7D%7BT_f%7D)
Thus, we compute the moles that are in 5.590 g of liquid mercury:
![n_{Hg}=5.590 gHg*\frac{1molHg}{200.59gHg} =0.02787molHg](https://tex.z-dn.net/?f=n_%7BHg%7D%3D5.590%20gHg%2A%5Cfrac%7B1molHg%7D%7B200.59gHg%7D%20%3D0.02787molHg)
Hence, we compute the required entropy change, considering the temperature to be in kelvins:
![\Delta _fS=\frac{0.02787mol*2.29\frac{kJ}{mol} }{(-38.9+273.15)K}\\\\\Delta _fS=2.724x10^{-4}\frac{kJ}{K} *\frac{1000J}{kJ} \\\\\Delta _fS=0.2724\frac{J}{K}](https://tex.z-dn.net/?f=%5CDelta%20_fS%3D%5Cfrac%7B0.02787mol%2A2.29%5Cfrac%7BkJ%7D%7Bmol%7D%20%7D%7B%28-38.9%2B273.15%29K%7D%5C%5C%5C%5C%5CDelta%20_fS%3D2.724x10%5E%7B-4%7D%5Cfrac%7BkJ%7D%7BK%7D%20%2A%5Cfrac%7B1000J%7D%7BkJ%7D%20%5C%5C%5C%5C%5CDelta%20_fS%3D0.2724%5Cfrac%7BJ%7D%7BK%7D)
Best regards.
Answer:
Winds that normally blow to the east get stronger, waters off the coast of North America cool down, and upwelling increases, improving the nutrients in the water.
Explanation:
The Elinino is a group of cyclones that are created by the building up of warm water that builds up along the equator in the Pacific. In the build-up of the Elinino, the warm ocean surface warms the atmosphere which then allows the air that is rich in moisture to rise rapidly and develop into a thunderstorm. This then causes Winds that normally blow to the east get stronger, waters off the coast of North America cool down, and upwelling increases, improving the nutrients in the water.
The same number of valence electrons exists in the same family of elements in the periodic table. In finding the answer to this problem, we just have to find the pair that belongs to the same family in the periodic table. The same family means same column. Among these, Oxygen and lead (Pb) are in the same family. This pair is the answer.
