Carbon dating is a process where scientists evaluate the percentage of Carbon-14 atoms that have decayed to Carbon-12. The process of changing
from Carbon-14 to Carbon-12 involves the atoms losing two neutrons.
What type of reaction occurs when Carbon-14 changes to Carbon-12?
O Single Replacement
O Fusion
O Decomposision
O Fission

explanation:

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 don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
