After reading that a solution is a homogeneous mixture, Hala wondered about her favorite morning drink, grape juice. Which statement about the solution that makes up grape juice is
true? *

1Sugar is one of the solvents, and grapes are one of the solutes.

2Grapes are the solvent and water is one of the solutes.
3Water is the solvent, and sugar is one of the solutes.
4Sugar is the solvent, and water is one of the solutes.​

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
