Complete and balance the following equations, and identify the oxidizing and reducing agents. (Recall that the O atoms in hydrogen peroxide, H2O2, have an atypical oxidation state.)
1. Complete and balance the following equations:
NO2−(aq)+Cr2O72−(aq)→Cr3+(aq)+NO3−(aq) (acidic solution)
Cr2O72−(aq)+CH3OH(aq)→HCO2H(aq)+Cr3+(aq) (acidic solution)
BrO3−(aq)+N2H4(aq)→Br2(l)+N2(g) (acidic solution)
NO2−(aq)+Al(s)→NH4+(aq)+AlO2−(aq) (basic solution)
H2O2(aq)+ClO2(aq)→ClO2−(aq)+O2(g) (basic solution)
Express your answer as a net chemical equation including phases.
