Answer:
See below
Explanation:
<u> Name </u> <u>Formula </u> <u> Major species </u> <u> </u>
Zinc iodide ZnI₂ H₂O(ℓ), I⁻(aq), Zn²⁺(aq),
Nitrogen(I) oxide N₂O H₂O(ℓ), N₂O(aq)
Sodium nitrite NaNO₂ H₂O(ℓ), Na⁺(aq), NO₂⁻(aq)
Glucose C₆H₁₂O₆ H₂O(ℓ), C₆H₁₂O₆(aq)
Nickel(II) iodide NiI₂ H₂O(ℓ), I⁻(aq), Ni²⁺(aq)
- Glucose and nitrogen(I) oxide are covalent compounds. They do not dissociate in solution.
- The compounds containing metals are ionic. They produce ions in solution.
- ZnI₂ and NiI₂ produce twice as many iodide ions as metal ions.

Answer:
Dipole-dipole interactions
Step-by-step explanation:
Each molecule consists of <em>two different elements</em>.
Thus, each molecule has permanent <em>bond dipoles</em>.
The dipoles do not cancel, so the attractive forces are dipole-dipole attractions.
"Covalent bonds" is <em>wrong,</em> because there are no bonds between the two molecules.
There are dipole-induced dipole and London dispersion forces, but they are much weaker than the dipole-dipole attractions.
