2 answers:
Answer:
1. Fractional distillation
2. Evaporation
3. Centrifuge
4. Fractional distillation
5. Electrophoresis
Explanation:
Two miscible (easily mixing fluids) are separated according to the difference in the boiling points. Thus, fractional distillation is used. This uses the phase equilibria between the liquid entering the plate and the vapor leaving the distillation plate.
Sometimes a reflux is needed to separate the substances and produce a pure substance and preserve heat.
Evaporation will work for a salt and water solution. The water is simply boiled off. What remains is the
Lastly, proteins in blood are separated by gravity in a centrifuge.
Electrophoresis separates amino acids according to their charges.

Answer:
28.7664 kJ /mol
Explanation:
The expression for Clausius-Clapeyron Equation is shown below as:
Where,
P is the vapor pressure
ΔHvap is the Enthalpy of Vaporization
R is the gas constant (8.314×10⁻³ kJ /mol K)
c is the constant.
The graph of ln P and 1/T gives a slope of - ΔHvap/ R and intercept of c.
Given :
Slope = -3.46×10³ K
So,
- ΔHvap/ R = -3.46×10³ K
<u>ΔHvap = 3.46×10³ K × 8.314×10⁻³ kJ /mol K = 28.7664 kJ /mol</u>
