Does having an oxidizing agent and a reducing agent present automatically mean that a redox reaction will take place?

2 Fe (s) 3Ni C12 (ag) 2 FeCl (a q) 3Ni (s) CO (g) H,0 (g) CO (g) H,(g) 2Na (s) C12 (g) 2Na Cl (s) redox reaction? O yes reducing agent: oxidizing agent: redox reaction? O yes reducing agent: oxidizing agent: redox reaction? O yes reducing agent: oxidizing agent:

Consider the following balanced redox reaction Mn^2+ (aq) + S_2 O_8^2- (aq) + 2H_2 O (1) rightarrow MnO_2 (s) + 4H^+ (aq) + 2SO_4^2+ (aq) Which of the following statements is true? Mn^2+ (aq) is the oxidizing agent and is reduced. Mn^2+ (aq) is the oxidizing agent and is oxidized. Mn^2+ (aq)) is the reducing agent and is reduced. Mn^2+ (aq) is the reducing agent and is oxidized. Manganese does not change its oxidation number in this reaction.
