Question

Balance the following half-reactions by adding the appropriate number of electrons. Which are oxidation half-reactions and which are reduction half-reactions? Use the left and right arrow keys to move the cursor out of a superscript or subscript in the module. Add electrons by typing e^- with the appropriate coefficient. For example, to add 2 electrons, type 2e^- on the appropriate side of the equation. Fe2+(aq) rightarrow e- + Fe3+(aq) AgI(s) rightarrow e-1 + Ag(s) + I-(aq) VO+2(aq) + 2H+(aq) rightarrow VO2+ + H2O(l) I2(s) + 6H2O(l) rightarrow 2e- + 2IO-3(aq) + 12H+(aq)

Explanation / Answer

b) 1 e on left side c)1 e on left side d) 7 e on right side.
