Answer 1

4Na + O2 =2Na2O                                                                    Mg+F2=MgF2                    
2Ca + O2 = 2Ca O                                                                                                               2Al +3 Cl2 =2AlCl3                                                                                                              2K + I2 =2K I

Answer 2

4Na + $O_{2}$ ->2 $Na_{2}O$
Al + 3Cl -> $AlCl_{3}$
Mg + 2 $F_{2}$ -> $MgF_{2}$
K + I -> KI 
2Ca + $O_{2}$ -> 2CaO
