Solution

A reaction that involves oxidation and reduction of the reactants is known as a redox reaction. Addition of oxygen or removal of hydrogen is known as oxidation, addition of hydrogen and removal of oxygen is known as reduction. The given equation is:

$ZnO + C \to Zn + CO$

The substance oxidised: C (Addition of oxygen)

The substance reduced: ZnO (Removal of oxygen)
