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:
Volume of stock solution needed = 6.0299 mL
Explanation:
<u> </u>Dilution consists of lowering the amount of solute per unit volume of solution. It is achieved by adding more diluent to the same amount of solute.
This is deduced when thinking that both the dissolution at the beginning and at the end will have the same amount of moles.
<u>Data:</u>
M1 = 6.01 M stock solution concentration
M2 = 0.3624 M diluted solution concentration
V2 =100 mL diluted solution volume
V1 = ? stock solution volume
M1 * V1 = M2 * V2
