What can information can i obtain from these chemical equation?
CuO + 2HCI -> CuCI2 + H20
CuO + 2HCI -> CuCI2 + H20

We would know a bit more if the state symbols were included. Probably....
CuO(s) + 2HCl(aq) --> CuCl2(aq) + H2O(l)
CuO is the basic anhydride of copper((II) hydroxide and therefore behaves much like a base when reacting with hydrochloric acid, that is, a salt and water are produced. The salt, CuCl2 is soluble in water and therefore exists as Cu2+ ions and Cl- ions. The Cl- ions come from the HCl(aq) which exists in solution as H+ and Cl- ions. The water is undissociated and comes from the solid CuO and H+. CuO is insoluble in water. A better representation of the reaction is the ionic equation in which everything that exists as an ion is written as an ion.
CuO(s) + 2H+ + 2Cl- --> Cu2+ + 2Cl- + H2O(l)
=========== Follow up =============
If abcd... is going to give a "word equation", then at least get the names correct. Copper exhibits more than one oxidation state and therefore, according to the Stock system, a Roman numeral is required in the name. CuO is copper(II) oxide, and CuCl2 is copper(II) chloride.

The chemical formula is symbolic rendering of the chemical reaction in which the reactant organizations are given around the left side and the product organizations around the right hand side. Molecular size for that water molecule H2O, for that ammonia molecule NH3.

the word equation is copper oxide + hydrochloric acid -> copper chloride + water

Copper (II) oxide is basic in nature.
