the two process that occur in a cell are
oxidation: this is loss of electron by electrode. the metal electrode loaes electrons and get oxidized and forms ions
the ions get migrated to solution
Reduction: here the ions present in solution gains electron and get deposited on electrodes.
so gain of electrons is by ions
electrode gains electrons is where reduction occurs, and the half cell in which the electrode loses electrons is where oxidation occurs.
Atoms of one element are converted to atoms of another element through transmutation or nuclear transmutation.
I think the answer is 98 grams
yes 89.75 sorry I'm not the best at math you should look on the internet
