Three students are mixing the same type of solute in 500 ml of water. Jessica is heating her solution, Larry left his on the counter at room temperature, and Hunter is heating his solution while stirring it

See explanation below

Explanation:

The question is incomplete, but here's the missing part:

"Which ranks who would fully dissolve the solute, from first to last?

a. Larry → Jessica → Hunter

b. Hunter → Jessica → Larry

c. Jessica → Hunter → Larry

d. Hunter → Larry → Jessica"

Now, in order to know this, we need to know how the solubility of a compound increase.

The solubility of a compound (assuming is being dissolved in 100 g of water) always increase with the temperature, in general terms. The ideal scenario is that the solute of the solution, does not dissolve in in low temperatures, and begin to dissolve when the temperature is increasing.

This is known as solubility curve, and you can look into that in several places.

Now returning to this question, we have three students with the same solution, and same volume. However the three of them work with that as they want to.

Jessica decides to heat the solution without doing any further action. Larry decides to leave the solution at room temperature, and Hunter heats the solution and keeps stirring it.

According to all this scenario, we can say that Larry would be the last, because the solution he has, remains in the same conditions and he didn't do anything else, so, his solution would not dissolve.

Now, both Jessica and Hunter heat their solution, but Hunter decides to stir the solute while it's heating. The only fact he did this, put him in the first place because the stirring of a solute in solution increase the reaction speed and promotes a better and quick dissolving of the solute into solution. And with this Jessica will be the second.

So the correct order would be:

Hunter > Jessica >>> Larry

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
