Explanation:
Answer:
-1.84 V
Explanation:
Eocell = Ecathode - Eanode
From the equation (the one that they give us), we can see that Cl2 is being reduced (it is gaining electrons).
Reduction always happens at the cathode, so we now know that the standard reduction potential of Cl2 is the Ecathode value
So, we can set up the equation like this:
3.2 V = 1.36 V - x
Solving for x gives us:
x = -1.84 V

the balanced equation for formation of potassium oxide is as follows
4K + O₂ --> 2K₂O
molar ratio of K to K₂O is 4:2
when 4 mol of potassium reacts, 2 mol of potassium oxide is formed
when 4 mol of K reacts - 2 mol of K₂O
when 1.52 mol of K reacts - 2/4 x 1.52 = 0.76 mol of K₂O
0.76 mol of K₂O is formed
