Answer: The oxidation half reaction for the given reaction is

Step-by-step explanation:
Oxidation reaction is defined as the reaction in which a substance looses its electron. The oxidation state of the substance gets increased.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

For the given chemical equation:

Oxidation half reaction:

Reduction half reaction:

Zinc is getting oxidized and hydrogen is getting reduced.
Hence, the oxidation half reaction for the given reaction is
