Sublimation takes place when an element or compound changes directly from a solid into a gas without passing through the liquid state....
this is what i found i do not know much about dry ice but i hope this helps you!!!

Seven valence electrons are present in the 'Lewis structure' for the given chlorine atom
A Chlorine atom has total 17 electrons in total. In the 'first orbit' 2 electrons, 10 electrons in the 'second orbit' and finally 7 electrons in the last orbit. As Chlorine is a Group 7 element, chlorine will have 7 'valence electrons' in its outermost orbit. While drawing the 'Lewis structure' of Chlorine we shall put seven dots that is the electrons or valance electrons around the symbol of Chlorine (CI).
<h3>
What are Valence electrons ?</h3>
The electrons in an atom's outermost shell, or energy level, are called valence electrons. For instance, the valence electrons of oxygen are six, with two in the 2s subshell and four in the 2p subshell.
- An atom's outer shell electrons, known as valence electrons, can take role in the creation of chemical bonds. When two atoms establish a single covalent bond, normally both atoms contribute one valence electron to create a shared pair. The ground state of an atom is its state with the least amount of energy.

Yea lol do that and maybe 71
A proton (H⁺) is transferred from the hydrochloric acid to the water molecule.
<h3>What is Bronsted-Lowry theory?</h3>
Bronsted-Lowry theory is used to classify acids and bases.
- Acid: is a substance that donates H⁺.
- Base: is a substance that accepts H⁺.
Hydrochloric acid is an acid and when it reacts with water, it transfers an H⁺ ion, according to the following equation.
HCl + H₂O ⇒ Cl⁻ + H₃O⁺
A proton (H⁺) is transferred from the hydrochloric acid to the water molecule.
