Answer:

Well you tell us. Which one does NOT conserve mass and charge.....?

Explanation:

#HCl(aq)+H_2O(l)rarr Cu^(2+) + 2NO_3^-#

#Ca(OH)_2(s) stackrel(H_2O)rarr Ca^(2+) +2HO^-#

#Ca(NO_3)_2(s) stackrel(H_2O)rarr Ca^(2+) +2NO_3^-#

#NH_3(aq) +H_2O(l) rightleftharpoonsNH_4^+ + HO^-#

And one of these things is not like the other ones.........
