WebExpert Answer 100% (2 ratings) Transcribed image text: Consider the following reaction: 2 Al (s)3 CuCl2 (aq) -> 2 AlCl3 (aq) + 3 Cu (s) Fill out the table below. All oxidation numbers should include a sign (unless the answer is 0) and the sign should come before the number. WebTo balance a redox equation using the half-reaction method, the equation is first divided into two half-reactions, one representing oxidation and one representing reduction. The equations for the half-reactions are then balanced for mass and charge and, if necessary, adjusted so that the number of electrons transferred in each equation is the ...
