How do you balance this redox rxn?

Al + HNO3 ----> Al(NO3)3 + NH4NO3 +H2O

  • chemistry - ,

    Two things are wrong with that equation:
    (a) Aluminum does not 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.
