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

Black cupric oxide solid is mixed with hydrochloric acid to form a green cupric chloride salt solution and water.

As you can tell Andrew is serious when it comesto striving for accuracy. In this picture Andrew is measuring out hydrochloric acid in a cylinder.




DOUBLE REPLACEMENT
It is a transfer of electrons and these particular products formed because Cu has a positive 2 charge and O has a negative 2 charge. When mixed with HCl (H having a 1 postivite charge and Cl a negatvie 1 charge) the electrons transfer and form the products.
