2). 2KClO3 → 2KCl + 3O2

3). 2NaCl + F2 → 2NaF + Cl2

4). 2H2 + O2 → 2H2O

5). Pb(OH)2 + 2HCl → 2H2O + PbCl2

6). 2AlBr3 + 3K2SO4 → 6KBr + Al2(SO4)3

7). CH4 + 2O2 → CO2 + 2H2O

8). C3H8 + O2 → 3CO2 + H2O

9). 2C3H18 + 15O2 → 6CO2 + 18H2O

10). FeCl3 + 3NaOH → Fe(OH)3 + 2NaCl

11). 4P + 5O2 → 2P2O5

12). 2Na + 2H2O → 2NaOH + H2

13). 2Ag2O → 4Ag + O2
