3) Which of the following is an oxidation-reduction reaction? A) Cu (s) + 2AgNO3 (aq) →2Ag (s) + Cu(NO3)2 (aq) B) H2CO3 (aq) + Ca(NO3)2 (aq) → 2HNO3 (aq) + CaCO3 (s) C) AgNO3 (aq) + HCI (aq) → AgCl (s) + HNO3 (aq) - D) Ba(C2H302)2 (aq) + Na2SO4 (aq) →BaSO4 (s) + 2NaC2H302(aq) E) HCI (aq) + NaOH (aq) → H20 (1) + NaCl (aq) 3) Which of the following is an oxidation-reduction reaction?
