Question

. Which of the following represents a redox reaction?
a) NaOH + HCl → NaCl + H2O
b) BaCl2 + H2SO4 → BaSO4 + 2HCl
c) CuSO4 + 2H2O → Cu(OH)2 + H2SO3
d) Zn + 2HCl → ZnCl2 + H2

Answer 1

Answer:

Zn+2HCI->ZnCI2+H2

it represent redex reaction

Answer 2

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

• it is the redox reaction.

Half cell reaction are the given in.

             Zn→$Zn^{2+}$+$2e^{-}$

reaction to given

            $2H^{(+)}$+$2e^{-}$→H2
