A science teacher states if two ice skaters with approximately the same mass push against one another with the same force, they will move away from one another at the
same speed and same distance. What scientific evidence supports the teacher as correct?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

let that person have a turn to speak : )

you need to have a picture of the atom that way we can answer it
