Answer: The value of for the half-cell reaction is 0.222 V.
Explanation:
Equation for solubility equilibrium is as follows.
Its solubility product will be as follows.
Cell reaction for this equation is as follows.
Reduction half-reaction: ,
Oxidation half-reaction: ,
= ?
Cell reaction:
So, for this cell reaction the number of moles of electrons transferred are n = 1.
Solubility product,
=
Therefore, according to the Nernst equation
At equilibrium, = 0.00 V
Putting the given values into the above formula as follows.
=
= 0.577 V
Hence, we will calculate the standard cell potential as follows.
= 0.222 V
Thus, we can conclude that value of for the half-cell reaction is 0.222 V.
Carbon dioxide, or 
, is a pure covalent bond.
pure - it's non-polar, because it's a linear & symmetrical bond.
covalent - covalence is when 2 electrons are shared by a pair of atoms. in the case of carbon dioxide, it's three atoms with an oxygen atom on the right, an oxygen atom on the left, and a carbon atom smack in the middle. 2 of carbon's extra electrons are shared with the right oxygen, and 2 other extra atoms are shared with with left oxygen.
