Answer:
- Last choice: <em><u>- 3.72°C</u></em>
Explanation:
The freezing point depression in a solvent is a colligative property: it depends on the number of solute particles.
The equation to predict the freezing point depression in a solvent is:
Where,
- ΔTf is the freezing point depression of the solvent,
- Kf is the cryoscopic molal constant of the solvent, and i is the Van'f Hoff factor, which is the number of ions produced by each unit formula of the ionic compound.

Explanation:
Saturated solid/liquid solution is changed to an unsaturated solution by the dilution process.
When the saturated solution is diluted by addition large quantity of solvent it changed to an unsaturated solution.
Saturated solid/liquid solution can also be changed to an unsaturated solution by increasing the temperature or heating the solution.
A saturated solution is a solution where further solute will not dissolve in the solvent.
An unsaturated solution is a solution in which has the ability to dissolve more solute.
H is 4*10^6 M , OH is 2.5*10^-9 M
Answer:
Double bond
Explanation:
an alkene is a unsaturated hydrocarbon which means that it contain at least one double bond
