    Janu, Ladoo, et al. It helps us help you better if you use the same screen name.
    Look up the potentials, add the oxidation half to the reduction half to obtain Eocell. Then dG = -nFE

    ^Those are my friends they are different people with the same question

    Then you must be in the same room using the same computer so just talk to each other; you don't need to talk via computer.
