With the same initial solution of 0.75 moles formate and 0.85 moles formic acid to make a buffer solution. The Ka of formic acid is 1.8x10-4.You add 60.7g hydrobromic acid to this solution, what is the new pH?

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.

Its a hope this

The think of process to make something successful

Wow that a lot of text for my tiny so i no wanna answer
