The balanced chemical equation for the reaction between hydrochloric acid (HCl) and copper(II) hydroxide (Cu(OH)2) to form copper(II) chloride (CuCl2) and water (H2O) is:

2HCl + Cu(OH)2 -> CuCl2 + 2H2O

In this reaction, copper hydroxide reacts with hydrochloric acid to form copper chloride and water.
