Answer:
The moist filter paper is in charge of preventing evaporation and ensuring the proper saturation of the air of the chromatography chamber.
Explanation:
Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures.
A strip of moist filter paper is put into the chromatography chamber so that its bottom touches the solvent and the paper lies on the chamber wall and reaches almost to the top of the container.
The container is closed and left for a few minutes to let the solvent vapors ascend the moist filter paper and saturate the air in the chamber.
The moist filter paper is in charge of preventing evaporation and ensuring the proper saturation of the air of the chamber.
Pressure=hrg
pressure is great at the bottom because the weight lf water exerts pressure below the container due to the gravitational pull of the earth.
KE = (1/2) (mass) (speed)²
KE = (1/2) (20 kg) (40 m/s)²
KE = (1/2) (20 kg) (1,600 m²/s²)
KE = (10 kg) (1,600 m²/s²)
KE = 16,000 Joules
Answer:
B.Ionizing radiation is the correct answer.
Explanation:
Ionizing radiation has sufficient energy that it can convert atoms and molecules into ions.
It has a sufficient amount of energy that it can separate tightly confined electrons from the orbit of an atom and causing that atom to become ionized.
