Nernst equation for this cell reaction at 
:
![E_{cell}=(E_{Sn^{2+}\mid Sn}^{0}-E_{Zn^{2+}\mid Zn}^{0})-\frac{0.059}{n}log\frac{[Zn^{2+}]}{[Sn^{2+}]}](https://tex.z-dn.net/?f=E_%7Bcell%7D%3D%28E_%7BSn%5E%7B2%2B%7D%5Cmid%20Sn%7D%5E%7B0%7D-E_%7BZn%5E%7B2%2B%7D%5Cmid%20Zn%7D%5E%7B0%7D%29-%5Cfrac%7B0.059%7D%7Bn%7Dlog%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5D%7D%7B%5BSn%5E%7B2%2B%7D%5D%7D)
Where, n is number of electron exchanged and species inside third bracket represents concentrations in molarity.
Here, n = 2, 
and ![[Zn^{2+}]=2.5\times 10^{-3}M](https://tex.z-dn.net/?f=%5BZn%5E%7B2%2B%7D%5D%3D2.5%5Ctimes%2010%5E%7B-3%7DM)
So, plug in all the given values into above equation:
![0.660V=(-0.136V+0.76V)-\frac{0.059}{2}log\frac{2.5\times 10^{-3}M}{[Sn^{2+}]}](https://tex.z-dn.net/?f=0.660V%3D%28-0.136V%2B0.76V%29-%5Cfrac%7B0.059%7D%7B2%7Dlog%5Cfrac%7B2.5%5Ctimes%2010%5E%7B-3%7DM%7D%7B%5BSn%5E%7B2%2B%7D%5D%7D)
So, ![[Sn^{2+}]=4.2\times 10^{-2}M](https://tex.z-dn.net/?f=%5BSn%5E%7B2%2B%7D%5D%3D4.2%5Ctimes%2010%5E%7B-2%7DM)
As the value "0.059" varies from literature to literature and 
is most closest to 
therefore option (B) is correct.
Answer:
the scientific name of lion is
Panthera leo
So it’s OKAYYYYY ITS OKAYYYY
chlorine has the atomic mass of 35.5 and is a non metal in the halogen family
Answer:
Its molecules are made up of 60 carbon atoms joined together by strong covalent bonds. Molecules of C 60 are spherical. There are weak intermolecular forces between molecules of buckminsterfullerene. These need little energy to overcome, so buckminsterfullerene is slippery and has a low melting point.
