Examine the following half-reactions and select the strongest oxidizing agent among the species listed.
Cr²⁺(aq) + 2e^-

Examine the following half-reactions and select the strongest oxidizing agent among the species listed. Cr<sup>2+</sup>(aq) + 2e<sup>-</sup> Cr(s) ;E° = -0.913 V Fe<sup>2+</sup>(aq) + 2e<sup>-</sup> Fe(s) ;E° = -0.447 V Sr<sup>2+</sup>(aq) + 2e<sup>-</sup> Sr(s) ;E° = -2.89 V Co<sup>2+</sup>(aq) + 2e<sup>-</sup> Co(s) ;E° = -0.28 V A) Cr<sup>2+</sup>(aq) B) Fe(s) C) Fe<sup>2+</sup>(aq) D) Sr<sup>2+</sup>(aq) E) Co<sup>2+</sup>(aq)

Cr(s) ;E° = -0.913 V
Fe²⁺(aq) + 2e^-

Fe(s) ;E° = -0.447 V
Sr²⁺(aq) + 2e^-

Sr(s) ;E° = -2.89 V
Co²⁺(aq) + 2e^-

Co(s) ;E° = -0.28 V
