Select the correct, balanced molecular equation

Cu(OH)2(s) + HCl(aq)  ---> CuCl2(s) + 2H2O(l)

HCl(aq) + KOH(aq) ---> KCl(aq) + H2O(l)

CoSO4(aq) + 2NaOH(aq) ---> Co(OH)2(s) + Na2SO4(aq)

The bolded part of the equation is what the products should be (according to me), BUT I keep getting the answer wrong

1) percipitates are acknowledged
2) The equation is balanced
3) correct phases.

Is there something im doing wrong?
Thanks!

Your top equation is not balanced.

Cu(OH)2(s) + 2HCl(aq) ---> CuCl2(s) + 2H2O(l)

thank you!
Every equation is balanced now, but the problem still remains unsolved.
These are molecular formulas correct? I really don't see why I keep getting the question wrong

Here is a hint it gives me once I got the question wrong.

Be careful. Choices may be incorrect because of some crucial but easily overlooked detail. There is only one correct answer for each reaction. This form of equation may be referred to as a ''molecular'' equation in your text as distinguished from the ''complete ionic'' and ''net ionic'' equations.

CuCl₂ is not insoluble in water.  It should be aqueous.

Hmm.
I remember back in Chem 12, I do recall an exception with Cu. On my solubility chart, it says Cl- is insoluble with Cu+.

I just answers my question. Thank you very much!

That's as maybe, but you're not dealing with Cu⁺ here, but Cu²⁺.
