A strip of sodium metal is bombarded by violet light (wavelength = 410 nm) at a rate of 10,000 photons per second, which causes
Zarrin [17]

Answer:

The minimum energy required to eject an electron from sodium will be bigger.

Explanation:

red light has a higher wavelength, that mean that the energy that emitted is lower in comparison with the violet light.

If the rate of the photons is the same, 10,000 photons per second, that  means that the required energy to take an electron need to be bigger to have the same effect.

Hope this info is useful.

If the enantiomeric excess of a mixture is 75%, what are the % compositions of the major and minor enantiomer?
Maru [420]

Let us say that R is the major enantiomer, while S is the minor enantiomer, therefore the formula for enantiomeric excess (ee) is:

ee = (R – S) * 100%

 

Let us further say that the fraction of R is x (R = x), and therefore fraction of S is 1 – x (S = 1 – x), therefore:

75 = (x – (1 – x)) * 100

75 = 100 x – 100 + 100 x

200 x = 175

x = 0.875

 

Summary of answers:

R = major enantiomer = 0.875 or 87.5%

<span>S = minor enantiomer = (1 – 0.875) = 0.125 or 12.5%</span>
