Aren't they balanced?
no i don't think so
can you balacne theses

Ag2O -> Ag + O2
C6H6 +O2 -> CO2 + H2O
Al2O3 + C -> Al + CO2
The top two are balanced. I am wondering why you don't think so.

On the next, I will be happy to critique your work. You will get more out of it that way, rather than me doing if for you.
can you display how to do the first then i could catch on.
