Answer:
reacts to form carbondioxide
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 =
Since the decomposition of MgO is the reverse of the reaction you have given us. The sign will be reversed:
2MgO -> 2Mg + O2 = 1204 kJ
Divide by two:
MgO -> Mg + 1/2 O2 =
602 kJ
