2. For each starting material below, state whether it is acting as an oxidizing agent or as a reducing agent, find the number of equivalents per mole, and compute the equivalent weight for the change specified. (a) KMnO4 → Mn2+ (b) H2S → H2SO4 (c) KI → 12 (d) K2Cr207 → Cr3+ (e) NaH2AsO3 → NaH2AsO4 (f) KMnO4 → MnO2 (9) Na2S2O3.5H2O → Na2S406 (h) HNO3 → NO (i) H2O2 → H20
