Specify which of the following are oxidation-reduction reactions, and identify the oxidizing agent, the reducing agent, the substance being oxidized, and the substancebeing reduced. (Type your answer using the format [Ca]2+ for Ca2+. If the reaction is not an oxidation-reduction reaction, type none in the answer boxes for theoxidizing agent, the reducing agent, the substance being oxidized, and the substance being reduced.)(a) Cu(s) + 2 Ag+(aq) 2 Ag(s) + Cu2+(aq)oxidation-reduction reaction not oxidation-reduction reaction .oxidizing agentreducing agentsubstance being oxidizedsubstance being reduced(b) HCl(g) + NH3(g) NH4Cl(s)oxidation-reduction reaction not oxidation-reduction reaction .oxidizing agentreducing agentsubstance being oxidizedsubstance being reduced(c) SiCl4(l) + 2 H2O(l) 4 HCl(aq) + SiO2(s)oxidation-reduction reaction not oxidation-reduction reaction .oxidizing agentreducing agentsubstance being oxidizedsubstance being reduced(d) SiCl4(l) + 2 Mg(s) 2 MgCl2(s) + Si(s)oxidation-reduction reaction not oxidation-reduction reaction .oxidizing agentreducing agentsubstance being oxidizedsubstance being reduced(e) Al(OH)4-(aq) AlO2-(aq) + 2 H2O(l)oxidation-reduction reaction not oxidation-reduction reaction .oxidizing agentreducing agentsubstance being oxidizedsubstance being reduced
