I believe the answer is orbital hybridization theory
<span>Lewis structure of both is similar:
H : CI (hydrogen chloride)
</span>
<span>K : CI (potassium chloride)</span>
Answer is: CaCl₂(s), calcium chloride.
Calcium cations and chlorine anions have a crystal structure in this solid inorganic salt. Ions have <span>the ordered arrangement.</span><span>
Ethane (C</span>₂H₆) is gas, g is chemistry
abbreviations or physical state symbol for gas, gases do not have a crystal structure.
Methanol (CH₃OH) is liquid, l is chemistry abbreviations or physical state symbol for liquids, it do not have a crystal structure.
Calcium iodide is dissolved in water, aqueous solution
(aq) do not have a crystal structure.
Answer:
T° freezing solution → -11.3°C
T° boiling solution → 103.1 °C
Explanation:
Assuming 100 % dissociation, we must find the i, Van't Hoff factor which means "the ions that are dissolved in solution"
This salt dissociates as this:
SnCl₄ (aq) → 1Sn⁴⁺ (aq) + 4Cl⁻ (aq) (so i =5)
The formula for the colligative property of freezing point depression and boiling point elevation are:
ΔT = Kf . m . i
where ΔT = T° freezing pure solvent - T° freezing solution
ΔT = Kb . m . i
where ΔT = T° boiling solution - T° boiling pure solvent
Freezing point depression:
0° - T° freezing solution = 1.86°C/m . 1.22 m . 5
T° freezing solution = - (1.86°C/m . 1.22 m . 5) → -11.3°C
Boiling point elevation:
T° boiling solution - 100°C = 0.512 °C/m . 1.22 m . 5
T° boiling solution = (0.512 °C/m . 1.22 m . 5) + 100°C → 103.1 °C
