4. 6. For each of the following, assign oxidation numbers to each element in each species, and label with arrows the oxidation and reduction; write the oxidizing agent and the reducing agent. Do not use hand-in this question paper; re-write these equations on your own paper. Follow the example:

NO2 --> NO3^- + NO

N= +4 O= -2 N= +5 O=-2 N= +2 O= -2

Oxidizing agent = NO2 and Reducing agent = NO2

1. Mn^2+ + BiO3^ -> MnO4^- + Bi^3+

2. ClO3^- + Cl^- -> Cl2 + ClO2

3. PH3 + I2 -> H3PO2^- + I^-

4. ClO2 -> ClO2^- + ClO3^-

5. Zn + NO3^- -> Zn(OH)4^2- + NH3

6. Al + OH^- -> AlO2^- + H2
