4.-Double replacement the cation of one compound replaces the cation of another compound and vice-versa.

1.-Decomposition                            read number 2 above

2.- Double replacement                 see number three above

3.- Synthesis                                   see 1 above

4.- Single replacement                   see 3 above

5.- Single replacement                  see 3 above

6.- Decomposition                         see 2 above

7.- Synthesis                                   see 1 above

8.- Double replacement                see 4 above

9.- Synthesis                                  see 1 above

10.- Single replacement                see 3 above
