Answer:

Explanation:
Hello!
In this case, since the Gibbs free energy of any process is related with the enthalpy change, temperature and entropy change as shown below:

For a chemical reaction it is simply modified to:

Thus, since the enthalpy of reaction is given as -304.2 kJ and the entropy as -414.2 J/K (-0.4142 kJ/K), at 775 K the Gibbs free energy of reaction turns out:

Whose result means this is a nonspontaneous reaction.

<em>"Sedimentary rocks are formed by the pressure over millions of years of organic material, inorganic material, sediment of course , and earth piling up over itself. Metamorphic rock and igneous rock originate either below the surface where plants lived and creatures roamed, or the heat from volcanic activity transformed everything. Sedimentary rock formation is the only geologic activity that permits and allows organic material preservation and hence fossil formation." </em>- <u>Charles Snider, Co-Founder of American Geode (on Quora.com)</u>

Explanation:
Sea water has a <u>high amount of salt present</u> in it. The density of salt is <u>higher than that of water</u>. It <u>dissolves in water</u>, thereby increasing its density. Hence, this is why sea water has a higher density than tap water.
