Identifying Oxidizing and Reducing Agents

The nickel–cadmium (nicad) battery uses the following redox reaction to generate electricity:

Cd(s) + NiO2(s) + 2H2O(l) → Cd(OH)2(s) + Ni(OH)2(s)

Identify the substances that are oxidized and reduced, and indicate which is the oxidizing agent and which is the reducing agent.

What is the reducing agent in the following reaction?

2 Br–(aq) + H2O2(aq) + 2 H+(aq) → Br2(aq) + 2 H2O(l)

(a) Br–(aq), (b) H2O2(aq), (c) H+(aq), (d) Br2(aq), (e) Na+(aq)
