a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.

b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.

c = The reaction which involve the oxidation reduction are called redox reaction.

The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.

Explanation:

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Chemical equation:

Zn + 2H⁺ → Zn²⁺ + H₂

a= The oxidation state of zinc is changed from 0 to +2 so zinc get oxidized.

b= The oxidation state of H is reduced to +1 to 0. So hydrogen get reduced.

Redox reaction:

The reaction which involve the oxidation reduction are called redox reaction.

The given chemical reaction involve the oxidation of zinc and reduction of hydrogen that's why it is redox reaction.
