Which one of the following statements is correct about the
reaction below?
4 Cr(s) + 3 O₂(g) + 3 H₂O(l) → 4 Cr³+ (aq) +12 OH(aq)
A) Cr(s) is the oxidizing agent because it is gaining electrons.
B) Cr(s) is the reducing agent because it is being oxidized.
C) 02 is the reducing agent because it is reduced.
O D) O2 is the oxidizing agent because it loses electrons.
O E) H2O is the oxidizing agent because it gains electrons to
become OH-.
