Answer:
c. HF can participate in hydrogen bonding.
Explanation:
<u>The boiling points of substances often reflect the strength of the </u><u>intermolecular forces</u><u> operating among the molecules.</u>
If it takes more energy to separate molecules of HF than of the rest of the hydrogen halides because HF molecules are held together by stronger intermolecular forces, then the boiling point of HF will be higher than that of all the hydrogen halides.
A particularly strong type of intermolecular attraction is called the hydrogen bond, <em>which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond</em>, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.
It is merely being transfered through the friction to the match thus lighting it on fire.
Plants fertilized one per week with Super Plant Food Formula have been shown in testing to produce twice as much fruit as plants that are not.
That answer is the most scientific because it states the word "testing" and in science they do a bunch of test to make a scientific claim.
If you needed to make ultra-pure silver from crude silver, you would collect the pure silver metal from the cathode in an electrolytic cell. <span />
