The excited state electron configuration 1s2 2s1 2p3. explain what will happen sa the carbon returns to its ground state and write the ground state electron configuration

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.

i think it is true since you can test the answer and can use observations to complete it.
