Edit : original problem solved.
Could someone please show me how to write ionic equations (cancelling spectator ions)
the only thing i do not understand about this is that there will be the same of everything on each side? Does it have something to do with what state they're in?
E.g How would i write the balanced ionic equation for:
Fe2O3 (s) + 3H2SO4 (aq) -----> Fe2(SO4)4(aq) + 3H2O (l)
Thanks
