Explain how you can determine the electron configuration of an atom simply by looking at the periodic table

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the dissolution of polymer can be thermodynamically described in 2 steps.

the ratio of the conjugate base to the acid required to attain the desired ph.

the answer is c.the valence of the atoms combine .
