Fill in the blanks: lodine is [answer1] in pentane because they are both [answer2] (type) compounds kci has a boiling point of 1420°c and acetic acid has a lower boiling point of 116.2°c because the [answer3] bonds holding kci together are [answer4] than the [answer5] bonds which hold acetic acid molecules to one another.

answer1 = soluble

answer2 = nonpolar

answer3 = ionic

answer4 = stronger

answer5 = hydrogen

Explanation:

(answer1) Iodine is a solid and pentane is a liquid, so the answer is probably related to solubility

(answer2) Both iodine and pentane are nonpolar, which is a property that affects the solubility of the first in the second

(answer3,4, 5) Boiling point is related to the forces within a substance. The strongest forces in KCl are ionic bonds, which are stronger than the temporary hydrogen bonds in acetic acid.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
