Balancing Equations?

Ok I have Ca(OH)2(s) --> Ca(aq) + (OH)2(aq)

Now do I just do it like that or

2Ca(aq) + 2(OH)2 (aq)?

    That equation doesn't make any sense -- it says that you have this powder which all of a sudden dissolves into water that isn't there and splits apart. I think your confusion here probably comes from trying to balance the wrong chemical equation.

    You probably want the production of lime from calcium oxide. The equation for that looks like this:

    CaO (aq) + H2O <---> Ca(OH)2 (aq)

    You can see that this is balanced because there is one calcium, two oxygens, and two hydrogens on each side of the reaction.
