2

+3 -2
Al + O =
2

+7 -2
Cl + O =
2

+5 -2
Cl + O =
2

+2 -2
Fe + O =
2

Answer 1

+1 -2
Na + O =  Na2O
``````````
+2  + 1
``````````````
+2  -2 = 0


+3 -2
Al + O = Al2O3
 2 + 3
``````````
+6 - 6 = 0

+7 -2
Cl + O =  Cl2O7
2  +  7
````````
14 - 14 = 0

+5 -2
Cl + O =  Cl2O5
2 +  5
``````````
10 - 10 = 0

+2 -2
Fe + O = FeO
2  +  2
``````````
+4 -4 =0
