Which of the following equations is balanced correctly? a. 2 c2h2 + 5 o2 → 4 co2 + 2 h2o b. cl2 + 2 kbr → kcl + br2 c. 3 h2o → h2 + 3 o2 d. 2 c3h3 + o2 → 2 co2 + h2o

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

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.
