Asubstance has a triple point at −24.5 ∘c and 225 mmhg. what is most likely to happen to a solid sample of the substance as it is warmed from −35 ∘c to 5 ∘c at a pressure of 210 mmhg?

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

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.

it's filtration, but this is an assumption so my apologies if i got this
