identify the oxidizing and reducing agents. (Recall that the O
atoms in hydrogen peroxide, H202, have an atypical oxidation
state.)
a. NO2 (ag) + Cr2O,²- (aq) →
(acidic solution)
Cr** (ag) + NO3 (aq)
b. S (s) + HNO3 (aq) → H2SO3 (aq) + N½O (g)
(acidic solution)
Cr,0,²- (ag) + CH;OH(aq) → HCO0H(aq) +
C.
Cr³+(aq)
(acidic solution)
d. BrO3 (ag) + N½H4 (g) → Br (aq) + N2 (g)
(acidic solution)
e. ΝO (αaq) + Al (s )-ΝΗ (ag) + ΑIO, (ag)
(basic solution)
f. H2O2 (aq) + CIO2 (aq) → C1O2 (aq) + O2 (g)
(basic solution)
please do just a,c,e and f. please also do
