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:
True
Explanation:
Step 1: Find molecular formula of sucrose
C₁₂H₂₂O₁₁
Step 2: Convert moles of oxygen present to grams
1 mol O = 16 g O
11 mol O = 176 g O
Step 3: Find molar mass of sucrose
C - 12.01 g/mol
H - 1.01 g/mol
O - 16.00 g/mol
12.01(12) + 22(1.01) + 11(16.00) = 342.34 g/mol C₁₂H₂₂O₁₁
Step 4: Set up dimensional analysis
Step 5: Multiply/Divide and cancel out units
Grams of C₁₂H₂₂O₁₁ and grams of C₁₂H₂₂O₁₁ cancel out.
We are left with grams Oxygen
176/342.34 = 0.514109 grams Oxygen
