Pls answer the question
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:
The value of the Golden Igloo is $227.4 million.
Explanation:
First, we need to find the inner and the outer volume of the half-spherical shell:
The total volume is given by:
Where:
: is the inner volume
: is the inner radius = 1.25/2 = 0.625 m
: is the outer volume
: is the outer radius = 1.45/2 = 0.725 m
Then, the total volume of the Igloo is:
Now, by using the density we can find the mass of the Igloo:
Finally, the value (V) of the antiquity is:
Therefore, the value of the Golden Igloo is $227.4 million.
