#"CuO"("s")# + #"2H"^+("aq")# #rarr# #"Cu"^(2+)("aq")# + #"H"_2"O"("l")#

Explanation:

This reaction is a type of double replacement reaction called a neutralization reaction, in which the solid copper(II) oxide base plus hydrochloric acid produce a soluble salt, copper(II) chloride, and water.

Molecular Equation:

#"CuO"("s")# + #"2HCl"("aq")# #rarr# #"CuCl"_2("aq")# + #"H"_2"O"("l")#

Complete Ionic Equation

#"CuO(s)" + "2H"^+"(aq)" + color(red)cancel(color(black)("2Cl"))^-""("aq")##rarr##"Cu"^(2+)"(aq)" + color(red)cancel(color(black)("2Cl"))^-""("aq") + "H"_2"O(l)"#

Cancel the species that occur on both sides of the reaction. They are the spectator ions and do not participate in the reaction.

Net Ionic equation: Includes only the species that participated in the reaction.

#"CuO"("s")# + #"2H"^+("aq")# #rarr# #"Cu"^(2+)("aq")# + #"H"_2"O"("l")#
