# Which of the following is wrong statement?

$\begin{array}{1 1}(a)\;\text{Metals with negative SRP give }H_2\;\text{gas with normal acids}\\(b)\;Cu,Ag,Hg\;\overset{\overset{HCl}{\rightarrow}}{H_2SO_4}\;No\;rx_n\\(c)\;Cu,Ag,Hg\;\overset{\overset{HNO_3}{\rightarrow}}{oxidative}\;metal\;ion+NO\;or\;NO_2\\(d)\;Al,Zn,Fe,Sn\;\overset{\overset{HCl}{\rightarrow}}{H_2SO_4}\;No\;rx_n\end{array}$

## 1 Answer
