Answer:
Zn+2HCI->ZnCI2+H2
it represent redex reaction
The redox reaction is the (D) Zn + 2HCl → ZnCl2 + H2.
Explanation:
Redox reaction:
The redox reaction is to be a oxidation-reduction reaction is any chemical reaction in which, by the obtaining or losing an electrons, the oxidation number of a molecule and atoms or ion varies that is Redox reaction.
Zn + 2HCl → ZnCl2 + H2
Zn + 2HCl → ZnCl2 + H2
Half cell reaction are the given in.
Zn→[tex]Zn^{2+}[/tex]+[tex]2e^{-}[/tex]
reaction to given
[tex]2H^{(+)}[/tex]+[tex]2e^{-}[/tex]→H2
