Answer : F_2 reactant is reduced and Zn reactant is oxidized.

Explanation :

Redox reaction : It is a type of reaction in which an oxidation and reduction reaction takes palace simultaneously.

Oxidation : The loss of electrons or increase in the oxidation number is an oxidation.

Reduction : The gain of electrons or decrease in the oxidation number is a reduction.

The given balanced redox reaction is,

F_2+Znrightarrow ZnF_2

The oxidation number of F_2 = 0

The oxidation number of Zn = 0

The oxidation number of Zn in ZnF_2

x + 2(-1) = 0

x = +2

The oxidation number of F_2 in ZnF_2 = -1

That means F_2 is reduced due to decrease in the oxidation number from 0 to (-1) and ‘Zn’ is oxidized  due to increase in the oxidation number from 0 to (+2).

Therefore, F_2 reactant is reduced and Zn reactant is oxidized.
