14. balanced equation represents an oxidation-reduction reaction? BaCl2 + Na2SO4 BaSO4 + 2NaCl → C + H2O CO + H2 → CaCO3 CaO + CO2 → Mg(OH)2 + 2HNO3 Mg(NO3)2 + 2H2O → 15. In the reaction: 2H2S + 3O2 2SO2 + 2H2O, the oxidizing agent is → oxygen water sulfur dioxide hydrogen sulfide 16. What happens to reducing agents in chemical reactions? Reducing agents gain protons. Reducing agents gain electrons. Reducing agents are oxidized. Reducing agents are reduced. 17. Given the reaction: Which species undergoes oxidation? Mg(s) H+(aq) Cl-(aq) H2(g) Half Reactions An oxidation-reduction, reaction involves the transfer of electrons. Ex. Sodium transfers electrons to Chlorine The oxidation numbers of the atoms will change…. one goes up (oxidation) and one goes down (reduction) Reduction ___________________________________________________ ___________________________________________________ Reduction half reaction _______________________________________________ _______________________________________________ Oxidation
