Not sure about the "adding" part, but this makes sense:

H+ + Cl- + Na+ + OH- --> H2O + NaCl

You can't have plain Cl, must be Cl2.

To add equations you add left sides and right sides separately.

What are the equations you have to add?

First reaction is dissociation, not decomposition.

However, adding these two doesn't make sense, as these are apples and pears.

What is exact wording of the question?
