16)what type of reaction is this generic equation  AB+CD=AD+CB single displacement  decomposition combination. double displacement

Consider a double replacement reaction between Zinc (ll) chloride and sodium hydroxide: ZnCl2+NaOH ==> Complete the chemical equation by: 1. Rewriting it to include electrically-neutral ionic product formulas for each formula. To clarify instead of just writing the product formulas rewrite the entire equation. Concerning the "electrically neutral" part, you are reminded that if for example, Na + Cl2 ==> were your reactants, you would not predict NaCl2 as a chemical product because that is not an electrically neutral compound formula. The Na would have a +1 charge and, the Cl would have a -1 charge, 2 (-1) charges would give an overall -2 charge which would not produce an overall 0 charge. 2. Balance it. 3. Add subscripts (aq, I, s, or g) to show how the reactants combine and which product will precipitate to be collected as a solid. 4. Provide subscripts for both reactants and both products.
