Use bond energies, values of electron affinities, and the ionization energy of hydrogen (1312 kj/mol) to estimate δe for the following reaction. h2o(g) → h+(g) + oh-(g)

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

Change in speed or direction : )

12 is probably the typical age for a first kiss but i think its to young.

Is there any options, for this
