Answer: Option (a) is the correct answer.
Explanation:
Since, it is given that energy is absorbed by the water molecules resulting in a decrease in water's temperature, that is, there will also be a decrease in the energy of molecules.
As a result, molecules will come closer to each other. This means that the diagram (a) best illustrates the energy change of this dissolving process.
Surface current are caused by : D. Wind Forces.

Answer:
If you're just looking at the Lewis Structure from the perspective of the octet rule, it does appear that the structure is correct. Dinitrogen always has a lone pair of electrons which could conceivably be used for dative bonding as you suggest. So from that perspective there appears to be nothing wrong at all - other than that it doesn't exist in nature in this way.
Explanation:
it is called the partial pressure because it is pressure that is exerted by each gas in a mixture of gases if it occupy the same volume of it own. the the partial pressure of oxygen in the air sample above is 100 mm hg, that of carbon dioxide is 40 mmhg, for water vapor 47 mmhg. and that of nitrogen is 573 mmhg
