Homework Help: Chemistry

Posted by Val on Monday, March 22, 2010 at 11:33pm.

H1+(aq) + Fe(s) ==> H2(g) + Fe2+(aq)

I am trying to balance this equation...but I am not sure how to balance the H's.

I have the half rxns as
e- + H+(aq) ==> H2(g)
Fe(s) ==> Fe2+(aq) + 2e-

I multiplied the reduc. rxn (top) by 2 so I could get rid of the electrons...but then I am stuck on what to do with the Hydrogens and where to take it from there. Thanks!
