Which generalized equation represents a single displacement reaction?
question 12 options:

a +bc → ac+ b

a + b → ab

ab →a + b

ans is A +BC → AC+ B

a single element, B, is displaced in the reaction by another element, A. so its a single displacement reaction

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.
