Question
How do you balance this redox rxn?
Al + HNO3 ----> Al(NO3)3 + NH4NO3 +H2O
Al + HNO3 ----> Al(NO3)3 + NH4NO3 +H2O

Two things are wrong with that equation:
(a) Aluminum <b> does not </b> react with nitric acid.
(b) If we assume the reaction does occur, aluminum metal oxidizes (goes from an oxidation state of 0 to +3) but no element is reduced as required (experiences a lowering of its oxidation state).
It would be pointless to balance a chemical equation that is totally wrong.
