19. Single displacement reactions are always redox reactions (they include reaction between an element and a compound where they will take place of another element in that compound).
 20. It should be single displacement, where the displaced ion would form gas.

19.) Single-displacement is the correct answer.

20.) I am not sure, but Single-displacement is incorrect. At least you can cancel that one out.
