  1. 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.

  4. A trick is to just look for the element in the equation that is paired on one side, but not on the other. This being said, the following answers are correct.

    Redox:
    2CO+O2 = 2CO2
    Zn+CuCl2 = ZnCl2+Cu
    Non-Redox:
    SO3+H2O = H2SO4
    HCl+NaOH = H2O +NaCl
