(A) The reaction of $Zn$ with very dilute $HNO_3$ is given by: $4Zn + 10HNO_3 (very \text{ } dil.) \rightarrow 4Zn(NO_3)_2 + NH_4NO_3 + 3H_2O$. $Zn$ is a sufficiently active metal to reduce the nitrate ion to ammonium ion in very dilute acid conditions. $Pb$,$Cu$,and $Au$ do not produce $NH_4NO_3$ under these specific conditions.
