-- Posted by joker678 at 4:55 pm on Jan. 6, 2009 Mg(s) + Cu2+(aq) = Cu(s) thats the new solid formed right...? it was worth a shot -- Posted by boombabyboom at 4:57 pm on Jan. 6, 2009 I have a D- in chem. I've never failed anything before >_> -- Posted by joker678 at 4:59 pm on Jan. 6, 2009 Quote: from boombabyboom at 4:57 pm on Jan. 6, 2009 I have a D- in chem.

Mg -> Mg2+ + 2e- Cu2+ + 2e- -> Cu Overall therefore it'd be: Mg (s)  +  Cu2+ (aq) ->  Mg2+ (aq)  +  Cu(s)
