5. Write completely balanced half cell reactions for the electro
(i) moltenNaCl :​

Na+ + e- => Na

2Cl- => Cl2 + 2e-

Explanation:

Na is reacting in the negative electrode (cathode) and this is where reduction happens- gain of electrons

Cl is reacting in the positive electrode (anode) and this is where oxidation happens - loss of electrons

Pneumonic:

O - Oxidation

I - Is

L - Loss

R - Reduction

I - Is

G - Gain

no sé si entiendes español pero te daría la respuesta si lo supiera, pero lo siento mucho
