Answer:
The charge on each oxygen atom is -2 while overall charge is -6.
Step-by-step explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Chemical equation:
FeCl₃ + O₂ → Fe₂O₃ + Cl₂
Balanced Chemical equation:
4FeCl₃ + 3O₂ → 2Fe₂O₃ + 6Cl₂
This is the example of single displacement reaction. Oxygen displace the chlorine from iron and get combine with it.
The charge on each oxygen atom is -2 while on each iron atom is +3. Thus overall charge on three oxygen atom is -6 while overall charge on iron atom is +6. Thus overall compound will be neutral.
