According to the arrhenius theory, when a base
dissolves in water it produces
(1) co3 2– as the only negative ion in solution
(2) oh– as the only negative ion in solution
(3) nh4 + as the only positive ion in solution
(4) h+ as the only positive ion in solution

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.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
