Evaluate 12P2
P4 + HNO3 ---------> H3PO4 + NO +H2O -> P4 + H2O -> H3PO4 Then using hit and trial method P4 + H2O -> 4H3PO4 + 10[O] (addition of 10 atoms of oxygen i.e. nascent oxygen to make the equation balanced) -> HNO3 -> NO2 + H2O Again using hit and trial method
P4 + HNO3 ---------> H3PO4 + NO +H2O -> P4 + H2O -> H3PO4 Then using hit and trial method P4 + H2O -> 4H3PO4 + 10[O] (addition of 10 atoms of oxygen i.e. nascent oxygen to make the equation balanced) -> HNO3 -> NO2 + H2O Again using hit and trial method
