An electrochemical cell has the following standard cell notation.

mg(s) | mg^2+ (aq) || aq^+(aq) | aq(s)

write a blanked redox equation for the cell using the oxidation and reduction half reactions. (be sure to equalize charge by multiplying by the correct numbers before adding and simplifying)

Explanation:

The given following standard cell notation.  

Mg(s) | Mg^2+ (aq) || Aq^+(aq) | Aq(s)

Oxidation:

....(1)

Reduction:

...(2)

Overall redox reaction: (1)+2 × (2)

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
