Classify each of the following as a redox reaction or a non-redox reaction.

Zn+CuCl2 -> ZnCl2+Cu

HCl+NaOH -> H2O+NaCl

2CO+O2 -> 2CO2

SO3+H2O -> H2SO4

Here is a site that will show you how to assign oxidation numbers to each element. Do that with each equation. Redox equations will have some that change oxidation state; non-redox will not.

For example, the first one is a redox equation. Zn changes from zero on the left to +2 on the right. Cu changes from +2 on the left to zero on the right.
