Answer:

Weak acid + strong base gives water and a salt.

Explanation:

#H-C-=N(aq) + NaOH(aq) rarr NaC-=N(aq) + H_2O(l)#

Since we were axed for a net ionic equation, we could remove the #Na^+# ion, which, after all, was along for the ride:

#H-C-=N(aq) + ""^(-)OH(aq) rarr ""^(-)C-=N(aq) + H_2O(l)#

Are these equations balanced with respect to mass and charge?

Can you give the equivalent reaction between phosphoric acid, #H_3PO_4# and 1 equiv of sodium hydroxide?
