If 0.158 moles of nonane are combusted in excess oxygen gas according to the reaction below, what total volume of gas will be
produced at 26°C and 789 torr?
C9H20(1) +1402(9)— 10H2O(g) + 9CO2(g)

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the answer is definitely 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.
