Answer:
Yes, it is an redox reaction.
Explanation:
[tex]2Ag_{(aq)} +2HNO_{3}_{(s)} =2AgNO_{3}_{(aq)} +H_{2}_{(g)}[/tex]
In this reaction silver is oxidated to [tex]Ag^{+}[/tex] and [tex]H^{+}[/tex] is reduced to [tex]H_{2}[/tex]
reduction semi reaction
[tex]2H^{+}+2e=H_{2}[/tex]
oxidationsemi reaction
[tex]Ag_{s}=Ag^{+}+e[/tex]
global reaction
[tex]2Ag_{(aq)} +2HNO_{3}_{(s)} =2AgNO_{3}_{(aq)} +H_{2}_{(g)}[/tex]
