an experiment was conducted by measuring the change in temperature of solutions after mixing them together.

After figuring out the KJ/mol, write a net ionic equation for each mixture

1) hydrochloric acid and sodium hydroxide (net ionic equation?)

2) nitric acid and sodium hydroxide

3)acetic acid and sodium hydroxide

I am not sure what to do for these, I know what net ionic equations are, but i was also told not to write down net ionic equations when there is no reaction (solid) being formed. and there are no solids (or precipitates being formed) so I would assume to not write a net ionic equation for either of them.
