Cr2O72-(aq) + H2O2 + H+(aq) CrO5(dark-purple) + H2O(I) CrO5(dark-purple) + H2O2(aq) + H+ Cr3+(aq) + O2(g) Balance these net ionic equations and write them in the space below: Balancing hints: The first one of these reactions is not a redox reaction; to balance this reaction it is helpful to remember that CrO5 contains two peroxide ions (O22-) from the hydrogen peroxide and one oxide ion. The second reaction is a redox reaction and can be balanced using the half-reaction method.
