Vedclass · Answer

(C) Metals like $Mg$ and $Mn$ are highly reactive and can reduce dilute $HNO_3$ to produce hydrogen gas $(H_2)$.Specifically,the reaction is: $Mn(s) + 2HNO_3(dil) \rightarrow Mn(NO_3)_2(aq) + H_2(g)$.Other metals like $Cu$ are less reactive than hydrogen and do not displace it from dilute acids.$Zn$ with concentrated $H_2SO_4$ produces $SO_2$ gas instead of $H_2$.

Which of the following reactions can produce hydrogen gas?
