The R f value for substance B in figure 8.10 should be calculated. Concept introduction: The R f value or the retention factor is defined as the ratio of distance traveled by the spots by the distance traveled by the solvent. R f = Distance travelled by spot Distance travelled by solvent The more the compounds move, the higher is the R f value. Thus the polarity of the compound helps in deciding the R f value.

Question

Interpretation Introduction

Interpretation:

The Rf value for substance B in figure 8.10 should be calculated.

Concept introduction:

The Rf value or the retention factor is defined as the ratio of distance traveled by the spots by the distance traveled by the solvent.

Rf=Distance travelled by spotDistance travelled by solvent

The more the compounds move, the higher is the Rf value. Thus the polarity of the compound helps in deciding the Rf value.

Laser. Indicate the relationship between metastable state and stimulated emission.

The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1
