Which of the following is a redox reaction? More than one answermay be correct.

HBr(aq) + KOH(aq) → H2O(l) + KBr(aq) SO3(g) + H2O(l) →H2SO4(aq)

HBr(aq) + Na2S(aq) → NaBr(aq) + H2S(g)

NH4+(aq) + 2 O2(g) → H2O(l) + NO3–(aq) + 2 H+(aq)

2 Na(s) + Cl2(g) → 2 NaCl(s)

None of the above are redox reactions.
