Suppose that a thin-layer chromatography plate the solvent front migrates a distance of 14 cm, and two steroid spots move distances of (a) 6 cm and (b) 12 cm. calculate the rf values for each steroid.

A)

B)

Explanation:

RF value in thin-layer chromatography plate is defined as the ratio of distance moved by the steroid spot (A) to the distance migrated by solvent front(B)

Hence, mathematically

------Equation (A)

a) Here cm and cm

Substituting the given values in above equation, we get -

b) Here cm and cm

Substituting the given values in above equation, we get -

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
