In the oxidation-reduction reaction h2o + 2mno2 + zn → mn2o3 + zn(oh)2, the half-reaction of the zinc is? a. zn(oh)2 → zn + 2e- b. zn(oh)2 → zn + 2oh- c. zn + 2oh- → zn(oh)2 + 2e- d. zn + 2oh- + 2e- → zn(oh)2

D

Explanation:

2MnO2 + H2O => Mn2O3 + 2OH is the correct balanced equation. All others are missing or have incorrect coefficients.

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.
