I think the answer is D. Periods 6-7, Because t<span>he periods that would contain elements with electrons in s, p, d, and f orbitals are periods 6-7.

Answer:
It is prepared small amounts of hydrogen cloride for uses in the lab.
It can be "generated in an HCl generator by dehydrating hydrochloric acid with either sulfuric acid or anhydrous calcium chloride."
The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond.
CO2, is a covalent bond, which is the sharing of electrons, not transfer.
KBr, is an ionic bond, because (k) loses an electron to bromine.
So, our final answer is:- <span>(3) KBr</span>
Vapor pressure is **directly** related to the temperature of the liquid!! :)
