Four standard reduction potentials are given below. Al³+ (aq) + 3 e → Al(s) Br₂(aq) + 2 e 2 Br (aq) Cl₂(g) + 2 e2 Cl(aq) Pb2+ (aq) + 2 e →→ Pb(s) chemPad (a) Rank the following in order from weakest to strongest oxidizing agent: Al³+ (aq), Br₂(aq), Cl₂(g), Pb2+ (aq). (Use the appropriate <, , or > symbol to separate substances in the list. Include states-of-matter under the given conditions in your answer.)

Two standard reduction potentials are given below. Cd²+ (aq) + 2 e¯ → Cd (s) Ered 2+ Zn²+ (aq) + 2 e¯ Zn(s) Ered There is only ONE submission for each part. = -0.403 V = -0.762 V (a) Which is a stronger reducing agent, Cd(s) or Zn(s)? Cd(s) Zn(s) (b) Which is the most difficult to oxidize, Cd(s) or Zn(s)? Cd(s) Zn(s) (c) Is Cd(s) able to reduce Zn²+ (aq) in a spontaneous reaction? is able is not able (d) Is Zn(s) able to reduce Cd²+ (aq) in a spontaneous reaction? O is able is not able
