C8H17OH + 12O2 —> 8CO2 + 9H2O
I can’t see it so u won’t get and answer
Im not 100% sure, but I think the answer is C. If not, Im sorry for bothering you.
Solution :
A cell that is concentrated is constructed by the same half reaction for the anode as well as he cathode.
We know,
In a standard cell,
the reduction half cell reaction is :

The oxidation half ell reaction :

Thus the complete reaction of the cell is :

cell =
