Five graduate students prepare extracts from 5 different tissues. Each student measures the total amount of alcohol dehydrogenase and the total amount of protein in his or her extract. Which extract has the highest specific activity?
extract Total protein(mg) Total alcohol dehydrogenase activity (units)
A 300 60,000
B 200 80,000
C 3,000 90,000
D 5,000 100,000
E 1,000 200,000

B

Explanation:

If you convert all the options to standard form and compare the relative exponents and values, one can now decide which one is the highest.

A quick comparison shows that option B. This value thus represents the highest activity among the options listed in the question. Hence the answer provided above.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
