You got all of them except the 3rd one. Basically to balance an equation, the number of atoms on one side must equal the atoms on the other side. For example, in the first equation you have 1 K on the left side and 1 K of the right side. You also have 1 Br on the left side and 1 Br on the right side. etc.... So it's balanced because the number of certain atoms on left are the same as on the right.

What's going to happen when you have to take the test?
8. 2NH4Cl + Ca(OH)2 --> CaCl2 + 2NH3 + 2H2O
9. Zn + 2HCl --> ZnCl2 + 2H
10. Fl2 + 2NaCl --> 2NaFl + Cl2
11. CaO + SO2 --> CaSO3
12. 2CaSO3 + O2 --> 2CaSO4

Having other people do your homework is fun, isn't it?
11) CaO + SO2 => CaSO3
I'll give you one because it's Christmas. Enjoy!
