`2x -14 +2 =0 , " " x=+6`
`overset(+1)H-overset(-2)O-overset(-2)overset(O)overset(||)underset(-2)underset(O)underset(||)underset(x" ")(S)-overset(-1)O-overset(-1)O-underset(-2)underset(O)underset(||)overset(-2)overset(O)overset(||)underset(x" ")(S)-overset(-2)O-overset(+1)H`
`2x +2 -14 =0, " "x =+6`
`overset(+1)H-overset(-2)O-overset(-2)overset(O)overset(||)underset(-2)underset(O)underset(||)(S^x)-underset(-1)O-underset(-1)O-underset(+1)H`
