For cadmium, the molar enthalpy of fusion is 55 1g and the molar entropy of fusion is 10.42 J/mol*K. The molar enthalpy of vaporization is 889 /g and the molar entropy of vaporization is 96.1 J/mol K. Calculate the melting and boiling points.

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.

the answer is b & c i believe : )

the answer would be a
