একটি ছেলে Cu, Cu ^(+) এবং Cu ^(2+) এর ব্যাসার্ধ 0.096 nm, 0.122 nm এবং 0.072 nm রেসপি হিসাবে রিপোর্ট করেছে...

A boy has reported the radii of Cu, Cu ^(+) and Cu ^(2+) as 0.096 nm, 0.122 nm and 0.072nm respectively. However, it has been noticed that he interchanged the values by mistake. Assign the correct values to different species.

Cu^(2+) + Sn rarr Sn^(2+) + Cu E^@_cu^(2+)/cu = 0.34, E^@_Sn^(2+)/Sn = -0.16 . find deltaG^@

E^(@) of Fe^(2 +) //Fe = - 0.44 V, E^(@) of Cu //Cu^(2+) = -0.34 V . Then in the cell

CuF_(2) contains Cu^(2+) ions surrounded by six F^(-) ions, four F^(-) being at a distance of 0.193 nm other two at a distance of 0.227 nm. Thus, it should have the configuration.
