Question description

1.CuO(s) + Al(s) ----> Cu(s) + Al2O3 the two unbalanced half reactions for cadwelding are written below along with their respective standard reduction potentials. Balance the half reactions in acidic conditions, write the overall balanced redox reaction then calculate delta G standard in kJ/mol for the reaction as written.

CuO(s) ---> Cu(s)  E(standard)= + 0.62V

Al(s) ---->Al2O3 (s) E(standard) = -1.66 V
