Suppose you take a trip to a distant universe and find that the periodic table there is derived from an arrangement of quantum numbers different from the one on Earth.
(a) Assuming that the Pauli exclusion principle remains valid in the distant universe, what is the maximum number of electrons that can populate a given orbital there.
(b) write the electron configuration with the atomic number 8 in the periodic table?
(c) What is the atomic number of the second moble gas?
What is the main component of the first eluting peak and what percentage of the total absorbance at 300nm is due to this component?(assuming the light path- length = 1.0 cm)
what is the presentage compostition of both of the components, which is the limiting reagent (if there is) and what is the theoretical yeild of each of them.
