Describe how thin layer chromatography is used in the isolation and extraction of lipids​

Chemistry

BabaBlast [244]3 years ago
4 0

Thin layer chromatography(TLC) works with the principle of separation through adsorption.

It is used in the isolation and extraction of lipids through the following steps:

  • apply the lipid samples spots in the bottom of the plate.
  • also apply sample solution to the marked spot
  • pour the mobile phase into the TLC chamber and use a moist filter paper to cover it. this is done to maintain equal humidity.
  • then place the plate in the TLC chamber and close it with a lid.
  • the plate is immersed into the solvent (mobile phase) for its development. this is done, keeping in mind that the sample spot should be above the solvent.
  • once the sample spots are developed, they are removed and dried.
  • this is later viewed using the UV light chamber to see the isolation of the lipid sample.

Brut [27]

Answer:

The answer to your question is 75%

Explanation:

Data

Theoretical production = 4 moles

Experimental production = 3 moles

Percent yield = ?

Formula

Percent yield = \frac{Experimental production}{Theoretical production} x 100

Substitution

Percent yield = \frac{3}{4} x 100

Result

Percent yield = 75 %

Imagine that Ana has a block made of pure gold. If she cuts this block into two equal pieces, pick the statement that best descr
dimaraw [331]

Answer : The correct statement is:

The density of each piece is the same as that of the original block.

Explanation :

Intensive property : It is defined as a property of substance which does not change as the amount of substance changes.

Examples: Temperature, refractive index, density, hardness, etc.

According to question, if Ana has a block made of pure gold and she cuts this block into two equal pieces then the density of each piece is the same as that of the original block because density is an intensive property that does not changes until and unless material is changed.

That means density remains same as that of the original piece.

Hence, the correct statement is the density of each piece is the same as that of the original block.
