consider the incomplete reaction (partial ionic equation) given below:

a) cu^2+ + zn --> zn^2+ + cu

i) give the two half equations for this reaction; oxidation + reduction

ii) identify the chemical substance (species) that has undergone oxidation

iii) identify the chemical substance (species) that has undergone reduction

iv) identify (from the reactants) the oxidizing agent (oxidant) in this reaction:

v) identify (from the reactants) the reducing agent (reductant) in this reaction:

Explanation:

I)  Oxidation reaction : When there is an increase in oxidation state number.

Reduction reaction : when there is a decrease in oxidation state number.

II) Zinc metal has gone under oxidation, as its oxidation state is changing from 0 to 2+. Zinc metal is getting converted into zinc ions.

III) Copper(II) ion has gone under reduction, as its oxidation state is changing from 2+ to 0. Copper ions are getting converted into copper metal.

IV) is an oxidant.

Those chemical agents which get reduced itself and oxidize others is called  oxidizing agents.

V) is an reductant.

Those chemical agents which get oxidized itself and reduce others is called reducing agents.

im pretty sure its b
