• # question_answer Zn gives ${{H}_{2}}$ gas with ${{H}_{2}}S{{O}_{4}}$ and HCl but not with $HN{{O}_{3}}$ because- A) in electrochemical series Zn is above hydrogenB) $NO_{3}^{\Theta }$ ion is reduced in preference to hydronium ionC) Zn act as an oxidising agent when react with $HN{{O}_{3}}$D) $HN{{O}_{3}}$ is weaker acid than ${{H}_{2}}S{{O}_{4}}$ and $HCl$

$4Zn+10HN{{O}_{3}}\,\,\to \,\,4Zn{{\left( N{{O}_{3}} \right)}_{2}}+N{{H}_{4}}N{{O}_{3}}+3{{H}_{2}}O$
