Solution: Which of the following is an oxidation-reduction reaction? Ba(C2H3O2)2 (aq) + Na2SO4 (aq) → BaSO4 (s) + 2NaC2H3O2 (aq)H2CO3 (aq) + Ca(NO3)2 (aq) → 2HNO3 (aq) + CaCO3 (s)Cu (s) + 2AgNO3 (aq) → 2Ag (s)

Problem

Which of the following is an oxidation-reduction reaction? 

Ba(C2H3O2)2 (aq) + Na2SO4 (aq) → BaSO4 (s) + 2NaC2H3O2 (aq)

H2CO3 (aq) + Ca(NO3)2 (aq) → 2HNO3 (aq) + CaCO3 (s)

Cu (s) + 2AgNO3 (aq) → 2Ag (s) + Cu(NO3)2 (aq)

AgNO3 (aq) + HCl (aq) → AgCl (s) + HNO3 (aq)

HCl (aq) + NaOH (aq) → H2O (l) + NaCl (aq)
