Oxidation is the loss of electrons. Reduction is the gain of electrons.
Zn is +2 on the left and +2 on the right. H is +1 on the left and +1 on the right. O is -2 on the left and -2 on the right. Cl is -1 on the left and -1 on the right. Anything change? nope. So nothing is oxidized and nothing is reduced.
In the reaction ZnO+2HCl=ZnCl2+H2O what is oxidized and what is reduced?
