which one is common redox reaction?

2H2O2((l) ⟶2 H2O(l) + O2(g)

8 NH3(g) + 6NO2(g) ⟶7N2(g) + 12 H2O(g)

3NaClO(aq) ⟶2Nacl(s) + NaClO3(aq)

What is your definition of common? All three are redox reactions. NaClO, in my opinion, is the one most often used. H2O2 is the next. The NH3/NO2 is one I've not seen before.
